Guide to Transformer kVA Ratings — How to Determine What Size Transformer You Need
In many industries, including health care, manufacturing, electrical contracting, higher education and corrections, reliable, high-quality transformers are essential for keeping operations running efficiently. Large facilities and industrial processes require substantial amounts of power, and they need dependable transformers to convert the energy coming from the power plant into a form they can use for their […]
Read MoreGuide to Oil-Filled Transformer Maintenance
Regular maintenance is a major part of keeping your oil-filled transformers in good working condition. Without scheduled upkeep, your transformers will be more likely to experience issues that can snowball into larger operational problems, like system failure. You don’t have to rely on reactive or condition-based maintenance when taking care of your machinery. Staying ahead of any and […]
Read MoreDOE Efficiency Standards for Dry Type Transformer
More than 40% of the energy used in the United States is consumed by building operations, including the electrical equipment and appliances within those buildings. While this equipment is essential to daily functionality in homes and business locations, ensuring that these appliances use energy efficiently is also gaining importance. Since the Energy Policy and Conservation Act of […]
Read MoreGuide to Dry Type Transformers
Jump To: A transformer is a device that transfers energy from one alternating-current circuit to another. Dry type transformers are used for many applications to reduce the voltage of conventional power circuits. Learn more about what a dry type transformer does and where we use dry type transformers. What is a Dry Type Transformer? A […]
Read MoreIndicators That Dry Type Transformers Are Failing
Transformers should be built to last, and dry type transformers, in particular, avoid some maintenance issues that can occur with oil-filled transformers. However, some potential problems can still cause a transformer to fail. In this post, we’ll discuss these problems and explain how to tell if your dry type will stop working soon so you […]
Read MoreCopper vs. Aluminum Dry Type Transformer Windings
Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer — one that draws power from the source and another that transfers that power […]
Read MoreWhy Is My Dry Type Transformer Making a Loud Humming Noise?
A transformer may hum or buzz without signaling that it is malfunctioning. Many dry type transformers produce steady humming noises when magnetized and operating normally. However, if you hear a loud hum or a buzz that’s not usually present, it could signal an issue. 4 Reasons Dry Type Transformers Make Loud Humming Noises If you […]
Read MoreWhy Is Your Dry Type Transformer Overheating?
Since transformers convert high voltages into consumable power, they generate significant heat. This heat can significantly affect the transformer’s efficiency and will shorten its life span. With energy efficiency becoming a top priority in many of today’s power applications, choosing a dry type unit that can adequately meet the required power needs and subsequent thermal […]
Read MoreShould You De-Energize Transformers When Changing Taps?
Since the input power fed into a transformer may be lower or higher than the intended rate, transformers require adjustments to produce the correct secondary voltage. These fluctuations can occur for various reasons, including a power drop across a long distribution line or excessive consumption from one or more facilities. Since it is impractical and […]
Read MoreDo Oil-Filled Transformers Need a Containment Pan?
If your facility uses oil-filled transformers to convert energy and they contain more than 1,320 gallons of oil, you may be subject to the Spill Prevention, Control and Countermeasure (SPCC) Rule. The primary goal of the SPCC Rule is to contain oil discharges and prevent these discharges from reaching navigable waters and adjoining shorelines. Specific rules apply […]
