We are Doing Product Highlights Today! The OctoLight

When I was in college, my roommate and I were slightly addicted to 2 things: Dukes of Hazard reruns and infomercials. Having watched the “PushLight” special probably 75 times in the 2 years we live together, we decided to buy a pack and split them. We used them in our closets, the trunk of our cars, to walk down the hall at night.

When I was still in college, my roommate and I are super addicted to almost everything nice. But there are two things that stand out: Dukes of Hazard reruns and infomercials.

You bet we did it! Several years aog I just had a roas beef issue while catering to a certain party and in order for me to let the air out of the trunk, we need to tore the light out so that it would not totally drain the battery. Now, I am wishing that I still have a pack of the PushLights from my dorm mate so that I could light up my trunk the way I want it to be.

With this in mind, I was totally delighted when I finally received a certain email from a company customer: the DeArmond Tool.

the email said…

“here are the one of the pictures that we have to sow you one of your company cases that were being used in our product line. This was the prototype of the product we have been working on. We would like to appreciate the designer of this case. It totally gave our small product the touch of class it actually needs! The small light is capable of lighting an entire room!

How does the Electronic Key Ring Devices Work?

Just over the weekend, there was something happening that baffled me: I have beaten my boyfriend at the game of chess! One of the first words that came out of my mouth was “I won?” and “Did you let me win?” Because in reality, we have been playing a couple of chess games now for about 8 months and I kept on losing to every single game.

Until this weekend, we tried playing the Trivial Pursuit. However, he mopped the board with me but it is okay. I still beat him at chess. I did a small reflection thought. All the weeks of him teaching me the pitfalls and the falls of the game lead to me to making better game choices. It also guided me towards the strategy that I formulated in order to beat him. It also started to sink in: I am learning and I love learning. It is wonderful to discover how things are working and how they are made.

With this in mind, we will look at how some of the electronic equipment work:

For this article, we are going to look at the buttons placed on a keyfob electronics enclosure. One can see the different types of buttons existing everywhere: calculators, keyless remotes of the car, and the television remote. There is a rubber keypad with a conductive contact placed on its back. Once the button is pressed, the conductive contact suddenly meets the board and it started to send an electronic signal that is totally specific to the taskt aht was assigned to the circuit.

Let us take an very simple example, in a calculator, when you press the button that was labeled “1” it indicates the number one. When the button is labeled as “+” is signals the circuit to add, when you press “3” and finally the “=” sign it tells the computer to add the numbers you just keyed in.

In a similar way, in a keyless entry remote, pressing the button that was labeled “unlock” will lead to the activation of the circuit board and it will send a wireless signal to the system’s receiver. This is located in the vehicle and the electric shocks should be opened. This is what you call the key less entry.

There are companies that has an entire line of key ring style remote and these products are widely available in different sizes, styles, and colors. The companies can even print directly on the buttons of these keyfobs to be able to customize them for the project you will be needing them for. If you need help in narrowing down the selection, just contact the customer service representatives to help you in your inquiry.

What are the Needed Characteristics of Ink when Printing on Plastic Enclosures?

If you want to customize your enclosure printing using a permanent ink: you want it to meet your expectations. The ink should effectively cope with what the enclosure will be used into.

With this in mind, if you want the print on your enclosure to last longer, it should be permanent and resistant to several environmental factors. This includes light and weathering that can be a result of extreme weather conditions. One of the main reasons is that one cannot have the enclosure to be printed again because once the original printing begins to fade, it cannot be reprinted again. Also one of the reasons for considering the ink that will be used is the volume: the company should round up all the products that have been sold. In terms of comparing the new printing with the old one is nearly impossible once the product has been removed from the vice.

Another thing to consider is the UV light and the extreme weather conditions that might be present in the area where the enclosures will be used. It can cause the coloring of the ink to start fading or discoloring. The separate cases can also have discoloration at a different rate, and it totally depends on what the exact conditions the ink was exposed to. One would potentially have to have a custom-color match for the ink for it to be effectively returned to the enclosure.

If you are looking for businesses who does customization printing on the enclosure, the durable electronic enclosure should have the plastic enclosure branded. The company should not want to look for a printing that can be damaged that easily once exposed to harmful elements. Most of these characteristics can be added up to have an increased protection for the ink on your end.

While there are some issues or problems that are not as big an issue basing on your final application, it still worth to ask if the cost of the printing is worth the hassle.

It is important for design engineers to effectively determine if the additional hassle for customization of enclosure is worth the company’s time and effort. At the end of the day, there are other options which your enclosure can be customized and not only for printing on it.

What does Relative Spacing and Customization in Electronic Enclosures Means?

There are a lot of articles on the internet that talks about how the relative design concepts works that utilizes spatial relationships in identifying the key locations of some enclosure cutouts.

Some of the enclosure manufacturing company’s engineers work with these concepts most of the time. They are more than willing to give help to consumers or companies that needs help with some design concepts. Most of the time a consumer will have a wide understanding on what they would be needing in terms of specific sized enclosure. A customer service representative can help the company or end user choose the proper enclosure that will be very suitable for the user or company’s needs. With this in mind, companies create a concept quote for different machining holes that are located in proper locations.

Once the customer is ready to place her order for the enclosure, the engineers can design or create a 3 dimensional drawing that will help in the programming of the CNC machines. One example to this is that when the end user or customers sends in a drawing, or calls the ballpark for some of the pricing modifications. Without the use of some of the specific dimensions, the companies can give pricing that is totally based on the space measured on top of the enclosure.

However, when the customer gives exact dimensions of the enclosure, it seems that the hole has the size of only 1/2” in diameter. Whilst the enclosure pricing can greatly vary by minimum amount of pennies basing on the size, another approach should be taken to make the large portion of the enclosure removed. This factor can highly affect the form and structure of the enclosure while it is clamped into the CNC machine so that the companies can use a quote that utilizes a very effective method in this specific example.

This is one of the reasons why companies are asking for the dimensional drawing of the enclosures at the time the order was placed. While the companies can give an exact quote of the enclosure basing on the estimated time frame on relative description, the companies would need to have a very precise measurement in order to remake the proper holes.

Majority of the companies can work on any format the companies provide for enclosure and they are always more than willing to help out the companies in customizing the electronics enclosure they are needing.

Utilizing Cable Glands to Properly Maintain NEMA Rating in Enclosures

When it comes to designing enclosures, cable glands are a must accessory. These small accessories can make its way through into a cutout or hole on the enclosure and it can make watertight seal of the NEMA or IP rated electronic enclosure. In addition to this, the cable glands accessory will allow the companies to customize their plastic enclosure in order for the enclosure to fit the board and the application in exact way as it is designed. But this will still make sure that the electronics are cool and dry inside the electronic housing.

The cable gland contains major three parts: a body with two threaded ends, cable nut, and a nut. An enclosure manufacturing company can machine the right sized hole into any flat surface of the electronics enclosure. With this, the cable gland will then be fitted inside the hole.

Before making sure that the gland is secured inside with the nut, a rubber gasket should be readily inserted that helps in protecting the enclosure from water ingress to take place. While on the opposite side of the threaded end, there should be an O-ring that is connected through the series of teeth. The cable nut should go over the O-ring and teeth, and then eventually the screws onto the threaded end.

Once the cable nut is already tightened, it can make the O-ring seal to be sealed around the wire, that will eventually create a watertight seal. Even if each cable gland can be securely sealed around only one wire, the multiple cable glands can be utilized on each electronic enclosure once more than one wire is utilized.

There are a lot of myriad sizes of different cable glands that are readily available. How to determine if the company is selecting the proper size for cable glands? First step is to determine and know the appropriate size of the wiring that will be used on the enclosure. This makes the company to be able to select the right cable gland that will hug the wiring very closely in order to be protected from water and dust ingress. Other enclosure manufacturer offers 7 different sizes of NEMA-rated cable glands that can be fitted inside a large range of wire sizes.

On a side note or tip in selecting the right wire: the wire size should be dependent on how much power that is needed to run inside and through the unit. Once that this has been established, and the rightful cable gland size is properly selected, the engineer can now continue building the enclosure. There are valuable resources in the internet (can also be found on different company websites) about rightful wiring selection.

The additional benefit of being able to use cable glands is it can also function as a strain relief. These can protect the wiring from bending, splitting, and fraying at some certain point of entry on the enclosure.

How to Effectively Design Electrical Enclosures for Debri Ingress Protection

There are several occasions where there are thousands of custom enclosures requested by companies to have environmental resistance requirements. And majority of the time these enclosures should only need the environmental protection for their equipment. With this in mind, companies use NEMA standards to clearly explain what the enclosure should be able to do in terms of protection to have clear understanding on what level of resistance it should have in terms of dust, dirt, or water ingress. But they also clearly note that they do not need to formally meet NEMA’s standards.

On some occasions, there are companies that needs to formally meet all the NEMA requirement in which the enclosure should undergo certain testing. With this in mind, the companies send their enclosure to third-party testing facility in order form them to have the formal certification that their enclosure has meet all the necessary requirements.

Understanding NEMA Classification

The published standards NEMA has set is primarily intended to have a certain quality of standards for an electrical enclosure. This also set in palce for them to promote what standardized product specifications electrical devices might need. Needless to say, NEMA’s role is to give standards for the manufacturing companies to adhere to a certain quality classification. NEMA should be able to deal with the following goals:

  1. For the enclosure to be able tor protect the personnel from dangerous internal parts of the equipment
  2. To be able to protect the equipment inside the enclosure from the harsh environmental elements.

How to Meet NEMA requirements

  1. Metal Sheet Enclosures

Needless to say, this type of electrical enclosure should be able to give protection from dust, debris, and water splashing or dripping. The sheet metal electrical enclosures are primarily designed to be able to meet the NEMA requirements in these type of enclosures: Types 1, 2, 4, 4X and 5. There are companies that needs enclosures that is needed to be immersed in the water, this type of enclosure is not suitable to type of companies that does marine offshore operations.

  • Custom CNC machined enclosure

If a company wants an electrical enclosure that is needed to be submerged in water, this is the right type for that company. This enclosure is primarily designed to meet the following NEMA types: 1, 2, 4(X) and 5. This can also be totally sealed with the proper and right accessories. The accessory types are the: waterproof gaskets, or o-rings. These accessories are made to give enough protection from deep water immersion thus meeting the requirement for NEMA type 6 enclosure.

  • Off the Shelf (OTS) Cast Enclosures with CNC Machined customizations

This type of enclosure will also meet NEMA Types 1, 2, 4(X) and 5 easily. This type of enclosure should be watertight with the proper accessories. This enclosure should come with minimal customizations as well as cutouts. Together with the right waterproof gaskets or o-rings, this enclosure should be able to meet the NEMA type 6P.

Transactive Energy Defined for Companies and Manufacturers

In line with the recent growing interest in having transactive energy or TE (as shown in New York’s visionary discussions; lead by national labs and implemented by United States) other countries are joining in the conversation such as companies from Denmark (PowerMatcher) and Australia (Power Ledger.)

The similar and almost the same strategies are being driven by the fact that these companies came to a realization that there should be newer approaches on how to efficiently and reliably integrate the existing distribute energy resources (DERs.) In order for them to effectively adapt to several changing preferences across electricity consumers. With this in mind, TE is one of the best solution there is.

Last 2011, the GridWise® Architecture Council (GWAC) planned and conducted an initial workshop to discuss TE. This workshop brought together several researchers and practitionares across different companies such as: utilities, vendors, labs and academia. Ever since, TE has shown great growth in subject to the annual conferences which constitute several participants: the Smart Electric Power Alliance (SEPA) Transactive Energy working group, and the National Institute of Standards and Technology (NIST) Transactive Energy Challenges.

The GWAC body defined what TE is: a system composed of economic and control mechanisms that gives provision for the dynamic balance of supply and demand happening across the entire electrical infrastructure that utilizes the value as one of the key operational parameter.

However, the definition is neither a specification or a given standard. TE is an effective approach to what describes the economic and control tools for effectively managing all elements within a given grid. Whether if it is a single building or different series of interconnected, internationally located utilities. One of the key operational parameter (what we call as “value”) does not have to be entirely economic. This can serve as a personal or individual comfort or it can go as global as delivering sustainable energy that helps in the improvement of people’s lives.

With this in mind, the delivery of electricity is about having the right balance. According to the recent research done by Erich Gunther, the former GWAC chairman emeritus, one of the pesky law of physics requires generation, movement and utilization of electricity be balanced at all times. Like in governance, policy makers should show equality in historical precedent that follows existing investment as well as local views.

In terms of regional or bulk level. One of the wholesale markets shows the reliability and efficiency of this system by assigning a good financial value in addition to the balance of supply and demand. As well as measuring some of the financial cost for some of the unforeseen uncertainties that are inherent from both sides that brings power delivery. Some of these markets and reliability form structures that effectively integrates the intermittent technologies like the grid-scale renewables and storage. This maintains the availability, affordability, as well as the reliability.

The Effect of Emergence of Dry-Type Outdoor

For decades now, the terminations of oil-filled have been the normal standard for high-voltage cables. However, being deviant from this former technology are being operated by some of the pre-molded dry-type outdoor terminations.

Last 2018, the 138kV are being pre-molded in areas where there is existence of dry-type outdoor terminates. These are being installed across three different regions in the world for the first time ever: Ansonia, Philippines, Malaysia, Connecticut. Each of these countries are having application of mechanical shrink installation technology to their new and existing grids.

In order to meet the increasing demand for some of the regional grid efficiency modernization. The 138kV termination brings about numerous benefits. One of which is the initial termination that being installed in some of the voltage level that utilizes the shrinkage of installation method. The 138kV dry-type outdoor termination constitutes a protection from harsh weather and the termination of this has brought great weather sheds that possibly lock out some of the environmental elements.

With this in mind, the rubber construction greatly offers some great benefits. Having dry-type terminations are 20% to 30% lighter and this allows companies for easier installation. Once the system is fully tested and it has been pre-expanded within the factory, it allows the creation of straightforward installations happening in the field. And it has greatly reduced the potential of having field damage and some devastations installation errors. This no longer contains oils and these terminations brought about avoidance of field damage from having any potential leak that also require maintenance. Because this can bring unexpected power outages.

This brings fewer parts that are needed to be installed and there are no more installation tools required. The weight has been greatly reduced, and this product should effectively and significantly decrease the risk of having field damage, installation time, and dependence on some of the jointers. This happens spontaneously while the improvement of the overall grid efficiency is happening. The flexibility and lightweight of the said equipment allows for the horizontal, vertical, and angled mounting positions. The installation of some of the oil-filled equipment usually requires machinery that are heavy in nature. This drives up some of the labor costs and it shows some limits in installation options due to the fact that the proximity to the energized overhead lines.

The installation of pre-molded dry type shows greater demand whereas the new grids are being currently developed while the level of electrification is now low. In some of the developing countries it is easier and cost-effective option.

While there is a transition happening in the U.S. is slower, the installation in systems such as Ansonia should be the start of the beginning for the utilization of Americans and move toward the dry-type single-piece pre-molded outdoor termination. Together with the shrinkage mechanical installation method in improving the grid efficiency.

Ways on Effectively Selecting Electronics Enclosure

There is once instance where a puppy playing for several us is so worn out that he was not even able to leave the couch. With this in mind, the owner was able to curl up with the puppy and make him relax without having the mind crazily roaming around the garden. While couching on the sofa, the owner was watching several commercials on TV. And it made her wonder, of all the commercials she just saw, how can customers decide on which products should they buy? Is it because of the benefits the commercial showed? How they can make sure that the product they are buying will deliver its promised benefits? Is there also a factor to what products their closest friends will recommend them? These are some of the questions the dog owner asked herself when watching those infomercials on television. 

This question also applies to the current dilemma of the companies that would like to have enclosures as a way to protect their equipment from certain elements. Designs and different classifications of sizes and colors, there are almost unlimited number of enclosures available in the market. The companies can call the manufacturing company to ask for the necessary information that they need in deciding which enclosure do they need for a certain operation task. There also customization needs a company might ask from the manufacturer. It is important to ask crucial information that will help them decide which enclosure is best suitable for them. 

With this in mind, there are two ways in making this selection easier for the companies: 

Step 1: Determine the size needed for the enclosure 

To begin the decision making process, the company should ask and determine the size of their equipment and components that will be housed inside the enclosure. Will they be needing a battery pack? If so, how many batteries does this battery pack should have? Aside from this what else does the enclosure should protect? Is it the LCDs, switches, lights? Some of the manufacturing companies offers enclosures that are easily customizable and can accommodate the needs of the companies. However, the customization of molded plastic enclosures requires a lot of time because it is time-consuming and most of the time more expensive. 

Step 2: Select the Right Type of Enclosure  

With the different needs for an electrical enclosure, the right type of enclosure should be determined in making sure that the characteristics of the enclosure will solve the needs of the company. Basing from the assembled project, the company should determine which equipment or component will be housed inside the enclosure. Also, the company should take note that they need to leave extra space inside the enclosure. Some enclosure companies make only external measurements. Once the company give the right measurement for the enclosure that they need, they should include the thickness of the material of the enclosure in their measurement. 

Importance of Transactive Energy for Companies and Manufacturers Alike

A DER can greatly impact the distribution grid in which they are installed regardless if a device or system will be able to supply energy or electricity to the grid that can make electricity more controllable. This can bring great impact regardless and irrespective of the side – in terms of customer point connection – on which they are installed or being used. 

Today, the distribution system that was being used and utilized decades is not design for usage in large-scale deployment DERS that comes with possibility of power flowing across and from different, multiple locations. The different impacts and several challenges the expansion of DER uses are broad. The examples are: 

  1. The reliance of several customers on different utility systems might be reduced in cases where the distributed generation is currently being paired with storage and some smart inverters. In return, this may bring great effect on the utility planning, operations and potential cost. 
  2. Some of the building owners can be compensated for making the alignment of their individual values that comes with holistic and general needs for distributions systems. The needs are being indicated by the varying production and consumption. 
  3. Some of the regulators are equipped to make the recovery of the shared cost in the electricity being transported with higher chances of granularity just to meet the values needed for the voltage variability. This also increases the effect on some of the operational costs and the frequency the operation of the equipment that will eventually result to reliability. 

With this in mind, the traditional generation should and must quickly adapt to a “duck curve” of a day’s utility load and this requires a steep ramp up or down. Because of the intermittence of the DER that suddenly increases or stops because of the wind variability, cloud coverage, or even time of the day. 

In addition to this, the distribution planning should effectively address the various increased risks in some reliability and related costs in a very constructive manner. This should also meet the regulator’s requirements for having economic fairness and some of the customer’s requirements of value. 

In line of this, TE effectively provides a new set of techniques companies can utilize in order form them to address numerous challenges: 

  1. The distribution engineers must ensure a safe and reliable operations that comes with solutions. These solutions should address the wires and non-wire different alternatives. 
  2. The GWAC roadmap effectively shows the vision on how to deploy the TE systems in a larger scale in an operational element and environment within the electric power system that efficiently facilitates the integration of DERs and other dynamic end uses. The example of this would be connection within buildings. 

In conclusion, the volume and capabilities of some of the installed distribution resources are prone to increase. And the need for the partnership among concerned parties that use the distribution grid should likewise potentially increase. This would eventually result in driving a further automated and consumer-centered operations.
