Power Transformers 101

Power transformers are conduits of electricity that increase or decrease voltage efficiently. These machines are used for transferring power from one circuit to another without changing the frequency.

When electricity comes into the transformer from the power source, it is called primary voltage. Any voltage leaving the transformer is called secondary voltage. Two examples of transformers include step-down, which lowers voltage, and step-up, which raises voltage.

Step-down transformers have higher primary voltage than secondary. These transformers are useful for situations requiring a lesser voltage than provided by the power source. 

Step-up transformers have lower primary voltage than secondary. When the power source is inadequate, these transformers can provide a boost.

Technically, all transformers can operate in both step-down and step-up modes, so the attribution is given based on how the transformer is being used. 

Other types of transformers include: 

  • Three Phase: used in three phase power systems; most cost-effective
  • Distribution: steps down the voltage for commercial or domestic distribution; operates 24/7 with 50 percent of a full load at maximum efficiency
  • Electrical Power: operates at high or peak load times with maximum efficiency at or near full load; used in a transmission network to step up or down voltage
  •  Instrument: C.T. and P.T. are used to lower high voltage and current to levels that can be measured by common instruments
  • Autotransformer: used in situations where the ratio between the high voltage and low voltage is less than two
  • Two Winding Transformer: used in situations where the ratio between the high voltage and low voltage is greater than two
  • Outdoor/Indoor: specifically designed for either application
  • Oil Cooled: refers to the cooling medium as transformer oil
  • Dry Type: refers to the cooling medium as air cooling
  • Core Type: contains two vertical legs with two horizontal sections called yokes; rectangular with a common magnetic circuit
  • Shell Type: has a central limb and two outer limbs with a double-magnetic circuit
  • Berry Type: core resembles wheel spokes with tightly fitted metal sheet tanks; oil used inside

Bus Plugs 101

Bus plugs are electrical instruments used to allocate power throughout large electrical areas. Flat copper conductor plates are enclosed in a metal casing, which creates a compact design. Bus plugs are typically beneficial in areas where cables cannot be wired in large industrial factories. The plugs are connected to busways or bus bars to provide electrical power when needed.

Since bus plugs have a wide variety of uses and advantages, they are considered more effective than electrical cables. Given that they have no physical electrical wires within the building, the entire system can easily be disconnected and rearranged to fit almost any floor plan.

Bus plugs are used for a variety of reasons, most notably:

  • Streamlined Current Distribution: Cabling is usually chaotic throughout most industrial plants. With various manufacturing aspects requiring electricity, distributing power can be a challenge. However, with bus plugs, electricity can be installed almost anywhere…and they are easy to move.
  • Safety and Security: Bus plugs are guaranteed to be safer than cable systems due to their metallic casing, which reduces wire damage and electrocution.
  • Easy Installation: Typically low in complexity, bus plugs do not require holes, cable cutouts, or any other special equipment. Ceilings or walls do not require support for heavy cables, and the installation time is relatively quick.
  • Energy Savings: Bus plugs are compact, which means the copper conductors are placed next to each other. Energy is conserved due to the reduction in induction resistance.
  • Flexibility and Maneuverability: More flexible than a typical cable system, bus plugs are light, easy to carry, and do not need ceiling or wall support. They can also be transferred to a new location effortlessly.
  • Compact, Concealed Design: Bus plugs appear much more organized than a traditional cable system since everything is concealed inside the casing. There are no more twisted, dusty, entangled bundles of cables running throughout your building.

Electrical components should only be purchased from a reputable company. At J&P Electrical, bus plugs are our business. Contact us today to learn more about our products and pricing.

Freedom Convoy That Protests Against Pandemic Restrictions Affects Consumer Pricing in U.S. & Canada

The number of COVID-19 cases is regularly decreasing, but some government officials are still trying to use the pandemic as a means of control. Recently, the Freedom Convoy took a stand against new vaccine requirements for the truckers who transport goods into Canada.

These truckers created blockades as a way to show their disdain for the requirement that truckers either quarantine 14 days when they go into Canada from the United States or be fully vaccinated against COVID-19. The requirement covers all truckers, regardless of if they’re from the U.S. or Canada.

There were more than 4,000 truckers who took place in the protest. The horns honking and blockades caused Ottawa businesses to close temporarily. The demonstrations also shut down the Ambassador Bridge and other border crossings crucial for trade.

Supply Chain Disruptions Impact Pricing

Commerce traffic flow through the Ambassador Bridge accounts for around $360 million worth of trade between these countries each day. Without this, transactions become critical for both Canada and the U.S. The disruption in the supply chain is impacting prices on a variety of goods in the U.S.

There’s some concern about similar protests happening in major U.S. cities, but those haven’t occurred yet. One reason for this is likely that states are starting to relax the mandates related to the pandemic.

In the electrical services industry, supply chain disruptions have caused an increase in pricing partly due to the cost of the wiring and other components. Therefore, taking steps to control the costs to consumers has to be a priority for service providers.

 At J&P Electrical, we can save your business 50-75% off the cost of buying new, as our specialty is salvaging and reconditioning heavy industrial electrical equipment. You can rest assured that our refurbished products are completely rebuilt, inspected, and tested, often mistaken for new surplus.

Bus Duct 101

Bus duct is a familiar sight to electricians, but what about the terms “busbar” or “busway?” Keep reading to learn about this vital aspect of electrical distribution.

The automotive industry first introduced busways in 1932; since then, it has expanded to serve many other industries. Busway is just another word for bus duct, which provides an alternative means of conducting electricity. Used in commercial and industrial settings, bus duct conducts electricity to power cables or cable bus.

Bus duct is comprised of sheet metal duct containing either aluminum or copper busbars in a grounded metal enclosure. Busbars are metallic strips or bars that conduct a substantial electrical current. Since bus ducts are flexible, they are easy to maintain and can handle different charging load requirements.

Bus duct is typically used where cable and conduit would be used in residential applications. Bus duct provides a high degree of electrical efficiency for both low- and high-amperage conditions. It’s also incredibly versatile, thanks to advancements such as elbows and offsets. These developments allow bus duct to adapt to directional changes.

To effortlessly meet load changes, tap-off units or new sections can be implemented. Some cases do require cable and conduit, however. For example, if a bus duct will be installed near corrosive vapors, it should not be used.

Planning ahead is vital when ordering bus duct for a specific use. Pay close attention to dimensions, note any bends, columns, floor elevation changes, route information, etc. Sketches of where the bus duct will flow are helpful. Standard bus duct can be ordered from inventory stock if the job is not too complex.

At J&P Electrical, we strive to provide the best electrical equipment possible. We have a massive supply of bus duct and plugs, along with other reconditioned products. Check out our inventory today!

Positive Outlook on the Horizon for Contractors

Thanks to the Infrastructure Investment and Jobs Act that was passed in November 2021, contractors country-wide are optimistic about their 2022 prospects. However, according to a survey report released by the Associated General Contractors of America, significant challenges still remain.

Over 1,000 American contractors were surveyed, and many were positive about the available bidding projects in 2022, since they have such a high dollar value. Respondents who expect the dollar value to expand is higher than those who expect it to shrink. Power construction is expected to benefit from the new law.

The authors wrote, “This represents a stark turnaround from the 2021 survey, in which contractors were bearish about the prospects for all but a few segments.”

Just under half of the respondents are looking to increase their employees by 10 percent or less, and more than a quarter of them anticipated bigger gains.

The report stated, “The construction industry is in much better shape overall than a year ago but there is wide variation among companies. For instance, small contractors, on average, have been slower to recover than larger businesses and are generally less optimistic about the 2022 outlook. While contractors in all regions expect 2022 to be a year of growth in business opportunities and employment, firms in the Northeast are less upbeat than elsewhere.”

Rising material process and supply chain dilemmas posed significant challenges which were exacerbated by the global pandemic. Higher prices were given for bids and contracts, with 44 percent noting longer completion rates. With increased supply chain issues, accelerated purchases were secured and winning contracts have turned to alternative suppliers.

The authors wrote, “While the past year has been filled with many challenges, technology has played an integral role in keeping people connected and businesses up and running. Firms are becoming more strategic about IT as they try to remain competitive in the current environment.”

With the rising use of technology comes an increase in electrical use. Connectivity is imperative, so many companies are utilizing electrical contractors to ensure their IT challenges are being handled. 

The report states, “The use of information technology, however, continues to pose challenges. Forty-one percent of contractors say it’s difficult to find the time to implement and train on new technology, 39% list keeping company data secure from hackers as one of their biggest IT challenges, and more than a third cite connectivity to remote job sites or communication between field and office as among the biggest IT challenges.”

Developing Electrical Code

Most standardized procedures aren’t developed overnight. Rather, they can take years to form with help from stakeholders, owners, employees, and more. With the invention of the Internet, advanced technology can simplify and complicate standards that might have already been in place.

Developing codes is an intricate process with much to take into consideration. First, there are many details to factor in while accounting for every step in the process. Then, other, perhaps surprising, aspects should be taken into consideration. Lastly, a trial run should be performed to ensure everything is working as it should, in accord with the overall intention. 

NFPA, the National Fire Protection Association, sets codes and standards in the electrical industry. To streamline the regulatory process, proposals (public inputs) are presented to the committee, answering every letter. Any changes are developed by the committee go through several steps:

  1. Revision stage: committee uses public input or their own discretion to create a vision or not, with reason.
  2. Draft stage: panel alters something from the first stage, if necessary, typically without public intervention.
  3. Reject stage: changes are analyzed using a new software called TerraView, designed to prevent conflicting actions. Comments made by the public can still be rejected during this stage or held for consideration during the next cycle of changes.
  4. Motion stage: those who might be disappointed with the process can file an online form to NFPA as a notice of intent to make a motion.
  5. Review stage: the NFPA Standards Council will assign a task group to review all motions and judge them based on their compliance. Once verified, the motion turns into a CAM, or Certified Amending Motion.
  6. Judgment: the Standards Council will have the last say; the results of the above process will be delivered to the panel, who will hear appeals and make decisions regarding the code.

At J&P Electrical, we respect the force of electrical power and its dangerous byproducts: shock and fire. Part of what we do is refurbish industrial electrical equipment using stringent standards. All electrical components are completely disassembled, then each and every part is cleaned, inspected, and repaired as needed. We then paint the product using an exclusive acrylic enamel chosen for its durability. The equipment is then reassembled and thoroughly tested to meet or exceed the manufacturer’s UL certification. The dielectric voltage withstands all tests, from phase-to-phase and phase to ground (neutral). The final product looks as close to new as possible. J&P Electrical stands behind its work; all our products come with a full one-year warranty.

Utilities See Shift in Winter Electrical Demand

According to a report by the American Council for an Energy-Efficient Economy (ACEEE), wintertime energy demand is set to rise due to the growing shift toward electrically-powered heating devices.

Traditionally, summer months have shown a higher peak in demand because of air conditioners. But now, the report predicts that a growing number of utilities nationwide will see electricity rise during the winter months instead.

One factor driving the shift is solar energy, which is becoming more popular. The demand for power from utility companies is diminished when solar power is implemented, reducing summer utility bills. Another factor of the reduced shift is the decrease in natural gas use. A growing number of homes and businesses are opting for electric heat pumps, electric space heaters, and electric water heaters, which are all typically used more in the winter months. These electrical devices can oftentimes be used instead of gas-fired appliances.

ACEEE has referred to state policymakers and regulators to create utility goals, which will reduce winter peak demand prices. Utility companies and city administrators should apply existing programs to correlate technology with new measures to reduce winter peak demand. Weatherization and home retrofit funding should also be a top priority.

Utility companies can implement energy-efficiency measures to winterize homes and enhance heating and energy use. Smart controls are one way utility companies can help customers monitor their usage. Also, demand-response measures such as electrical grid water heaters, electric vehicle charging, and battery systems can also help.

Homes that are better equipped to handle winter weather had higher-performing heat pumps and water-heating systems than others. These efficient homes could reduce winter peak by up to 12 percent. To add to that number, deep retrofits, smarter commercial HVAC controls, and intelligent technology systems can reduce peak demand during polar vortexes by up to 34 percent.

By implementing more efficient space heating, water heating, ventilation, lighting, and more, homes can reduce the electrical impact on the total grid.

Utility Transformers Strained by EV Growth

Electric Vehicle (EV) sales are growing. As an increasing number of people implement charging stations in their homes or businesses, nearby transformers are becoming affected. Overloads to the power supply, premature aging, and potential failures are all culprits for transformer damage.

Thankfully, an alternative exists: BESS, or Battery Energy Storage Systems. These devices can be especially beneficial when paired with photovoltaic (PV) panels.

A study conducted in 2020 by Milad Soleimani and Mladen Kezunovic titled, “Economic Evaluation of Transformer Loss of Life Mitigation by Energy Storage and PV Generation,” showed that using BESS and PV was economically more effective and mitigated transformer distribution due to decreasing prices.

Soleimani released a second study titled, “PV Generation, EV and Stationary Battery Optimal Control and Management in Distribution Grids,” which evaluated tactics to alleviate the loss of life on the transformer due to high voltage caused by EVs. It also investigated how transformers become overloaded from EVs. Because of potential failures, utilities and consumers typically experience excess expenses.

The study found that in areas with a large number of EVs, the use of BESS devices (with or without PV panels) decreased the risk of transformers becoming faulty. PV installations were also negligible in certain instances.

Since PV panels are more costly, combining solar power with BESS might not be practical without subsidies.

Soleimani suggests, “Utilities should be investors,” which can be accomplished by, “Developing and providing rebates and other incentive programs to motivate consumers to deploy these resources.” When the technology provides an ample return, utilities will benefit as well.

Billions of Dollars Set for Energy Projects via Infrastructure Bill

The United States Department of Energy (DOE) will fund a number of projects for electrical contractors thanks to an infrastructure bill signed into law on November 15, 2021. Numerous infrastructure projects will reap the benefits from a pot of more than $62 billion.

Some of the highlights include:

  • Investing over $7 billion in the supply chain to be used toward mining, sourcing, and recycling batteries. These are essential to power the grid with clean, affordable, and resilient energy.
  • Improving workforce development by investing hundreds of millions of dollars into the power grid, green building, and industrial sectors. Thanks to this funding, access to cutting-edge technology will spur training and career expansion.
  • Establishing an Energy Jobs Council to oversee the development and release of energy jobs and workforce data. By joining with stakeholders, decisions made by national, state, and local governments will be well-informed.
  • Providing grants to communities, cities, states, territories, and more through investments of $500 million or more into the State Energy Program, which develops and implements clean energy programs and projects, thereby creating jobs.
  • Devoting $550 million into the Energy Efficiency and Conservation Block Grant Program (EECBG).

Additionally, about $17 billion will exclusively focus on the electrical grid. The DOE said, “Extreme weather events like the Dixie Wildfire, Hurricane Ida, and the 2021 Texas Freeze have made it clear that our existing energy infrastructure cannot endure the impacts of climate change. Modernizing and expanding the electricity grid will make our energy sector more resilient, while enabling the buildout of affordable, reliable, clean energy.”

Of the $17 billion, $11 billion will go toward grants for states, Native American tribes, and utilities to increase electrical infrastructure against extreme weather, ransomware, and other issues. A $3 billion expansion of the Smart Grid Investment Matching Grant Program will be allocated, as well as a $2.5 billion Transmission Facilitation Program. Both programs aim to develop the power grid’s flexibility, upgrade to clean energy, deploy energy storage, and more.

Electrical Component Industry Shortages

By now, you’ve undoubtedly heard about the global supply shortages affecting nearly all industries. From vehicle manufacturing to computer components, nearly every business involved in overseas production has been affected.

The sudden rise in consumer electronics created a demand that the electronics supply chain couldn’t handle during the beginning of the pandemic. Due to worldwide shutdowns creating a pause in production, many companies are now playing catch-up. Moreover, tariffs were imposed on imported Chinese goods, which made the situation more challenging.

Raw materials and bulk electronic component shortages forced manufacturers to remain idle, many with half-finished products. The electronic components in high demand include capacitors, resistors, semiconductors, and other parts. Prices for several raw materials, including copper and steel, have doubled between 2020 and 2021. Semiconductors, microchips, and PCBs are all produced in Asia, so some manufacturers are looking to move their operations back to America to compensate.

Rising prices are also a factor; as demand rises and supply dwindles, costs increase. ElectronicsB2B reported that the semiconductor industry value is expected to increase by 11 percent from 2020 to 2027. Factors such as 5G-based automation, increased chip demand, and geopolitical issues could all play a massive role in whether the semiconductor shortage will ease up any time soon.

Labor shortages are also another large factor in part causing supply deficiency. The number of global working hours was decreased by 8.8 percent due to the worldwide coronavirus pandemic. 

Supply chains are the root of the shortages; the longer they are, the more susceptible to interruptions. This is partly why many suppliers are trying to relocate closer to home, called reshoring. With a more relative location, electrical components will arrive more punctually.
