Trump’s Order to Secure Power System Met with Favor and Uncertainty in the Utility Industry

On May 1st, 2020, Trump signed an executive order that established regulations of foreign-made equipment used in the United States bulk-power system. The order stated that Energy Secretary Dan Bouillotte would assemble a task force to oversee current policies that identify threats to securities and establish risk-management procedures to inform future procurement.

The order will have an impact on the future of power and electrical equipment purchases and possibly already installed and commissioned components at the generation and transmission level. “This is much broader; it reaches across the entire industry, not just the telecommunication infrastructure,” said Jason Johns, an energy market attorney with Stoel Rives, LLP. “At the same time, it is particularly broad and imprecise in terms of its application.’

The utility sector looks uncertain about how they will react to Trump’s order. It’s not clear how the mandate to secure the bulk power system from foreign cybersecurity attacks will affect the industry’s current infrastructure.

FERC Eases Regulations During COVID-19 Crisis

In this article, the Federal Energy Regulatory Commission (FERC) has initiated several steps to ease the regulatory burdens within the energy industry during the COVID-19 pandemic. One of the actions taken was moving most FERC employees to telework status, and technical and settlement conferences will be moving to video conferencing. 

FERC has been communicating with North American Electric Reliability Corporation and the Independent System Operator (ISO) and Regional Transmission Organization (RTO) and does not expect the crisis to impact the reliability of the bulk electric system.

As the FERC’s actions have been primarily concerned with easing regulatory burdens in the energy industry, it provides little relief to the financial and commercial sectors which are expected to be significantly impacted. Read more here.

What To Know About Measuring and Calculating Voltage Unbalance

It is important to understand what causes and how to fix voltage unbalance when dealing with a 3-phase electrical system. An example used in this article, for instance, shows a 480V nominal system that may measure phase-to-phase voltage: 463V, 482V, and 474V. The voltage unbalance will create a current unbalance or magnify any present current unbalance. According to the National Electrical Manufacturers Association (NEMA), for every 1% of voltage unbalance, 6% to 10% of current unbalance will be created. Voltage unbalances can be caused by several issues in the electric utility system. There is also a simple formula that can be used when taking phase-to-phase voltage measurements.

More Details Emerging on Digital Circuit Breakers

Many aspects of the electrical industry are all transitioning to a more digitized world which is now including the digital circuit breakers. Traditional mechanical circuit breakers have been around since the late 19th century when Thomas Edison first came up with the idea. Many homeowners are familiar with their circuit breakers when a fuse is blown and a person has to go looking in the dark for a switch to turn back on but, on a commercial aspect of the situation, it can be very dangerous, since commercial building’s electrical panels are slow enough that it still allows short circuits or arc flashes that can, in bad situations, even kill people. In January of this year, a company called Atom Power was the first to pass a test to bring digital circuit breakers to the market. In this article, the author further explains what makes a digital circuit breaker not only safer to utilize, but also can help eliminate other products that will be no longer needed. There is great potential in this new-found technology and surely Atom will not be the only company to continue research and development on these coming into the future.

Preventing Transformers from Exploding with Flexible Tanks

Transformer explosions are relatively rare, in fact, only less than one percent will explode. Although this percentage is very small when they do explode it can be very deadly and cause a large interruption with toxic fires or even oil spills. Canadian power supplier has collaborated with comapny ABB on a recent project to design a transformer tank to be more flexible to allow the pressure buildup from inside to expand without causing a rupture or explosion. To read more on how the ABB calculated the measurements and materials needs in order to create this new alternative read this article. This new product will be able to prevent most tanks from explosions thus creating a safer area for people who work near these transformers and also to the environment with less risk of oil spills and fires.

Electrical Component Shipments Rise in 2019

2019 has seen a somewhat steady growth in the shipments of electrical components, but June was a particularly great month for growth. According to the Illinois Business Daily, shipments of electrical components crossed the 1% growth mark, with a total dollar amount adding up to $11.8 billion in the month of June. The publication points out that the month of May before it saw a growth as well, only at half the amount of 0.5 percent. With technology advancing at an exponential trajectory with no foreseeable reason to stop we can only expect the number of shipments of electrical components and equipment to continue this path. One block in the road this year so far could be the tariffs on Chinese components and equipment coming into the United States, although with negotiations being so vague on that topic one can only speculate on the overall effect of such an installation.

Being Safe Around Circuit Breakers

Electricity is a dangerous concept and can be deadly if not handled properly. This may seem obvious but plenty of circuit boards these days are equipped with hundreds of amps, which can cause issues if not leveled properly by a current limiter. This is especially important due to the volatile nature of electricity and how often faults can arise.

In the Electronic Design article, the author spends time to explain exactly how these current limiters keep workers safe should any fault occur. You can see pros and cons to these bipolar junction transistors that are used in these limiters and what makes them work to prevent any pending disasters. Using handy charts and data tables the article makes it easy to have a better understanding of the properties so workers in the electric industry can properly work without endangering those around them.

Questions That Are Important to Ask When Buying Electrical Surplus Inventory Online


When a project is cancelled, warehouses are liquidated, or there are manufacturing overruns an electrical surplus inventory is generated.  Local surplus dealers were once the only sellers of electrical surplus inventory.  Today however, surplus equipment can be purchased through e-commerce platforms.  It is important you should proceed with caution when you come across surplus electrical component’s suppliers online; research and asking the right questions when buying online is crucial.  Below you will see how you should proceed when buying electrical surplus online.

Asking the right questions when buying surplus electrical equipment online helps you make the right purchase.  These questions should include:

  • Is the equipment a product that is from the original factory?
  • Will the new surplus inventory come in a sealed box?
  • Are there any visible structural damage like fractures or cracks in the equipment?
  • Do the products being sold contain any proof of safety and reliability?
  • Are there any signs of the equipment being burned in any way?
  • Has the equipment been in use, when?
  • Has the product failed?  What were the circumstances of the failure?
  • Do the products come with a warranty? When does the warranty expire?
  • Does the equipment have a period in which it can be returned if it does not meet the required standards?

Essentials to Consider When Purchasing Surplus Electrical Equipment

Voltage Ratings Input/Output

Know the voltage rating of the surplus electrical product as well as the voltage rating of your power sources.  This will determine if the equipment is suitable for your application.  Incorrect voltage ratings risk short circuiting, arching, and electrical fires.

Continuous Current Rating

The continuous current rating will allow you to know if the device will be able to perform properly in varying environments.  This is listed as Amperes.  They represent the continuous current that can be carried when used in the temperatures it is calibrated for.

Current Rating, Short-Circuit

Short-circuit current rating, SCCR, is a current rating that defines the maximum short-circuit current the product can safely handle.  Individual SCCR components for the electrical assembly are calculated to determine the SSCR for the entire electrical panel.

Electrical Current Frequency

Pay attention to the current frequency at which equipment or breakers are designed to operate properly.  The electrical current frequency determines the highest current a device can handle operating at without issue.
