Should 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 […]

Custom Bus Work on Transformers
When you purchase a replacement or retrofit transformer, most likely its high-voltage and low-voltage connections will not line up perfectly with your existing infrastructure due to differences in transformer models, ratings or designs. Low-voltage bus bar connections must line up perfectly with matching bolt holes and fasten together without distorting forces to ensure maximum conductance and prevent arcing. Each installation configuration is […]

How Reliable Is Your Transformer?
Most of the time, your transformer may seem like an inert apparatus tucked away in a cabinet. However, when energized, it is a vibrant, living thing, transforming and feeding electrical power at 60 Hertz to your facility. In addition to the metal windings and core, it contains organic materials in the form of insulation. However, like all living things, transformers age over time […]

When Do Most Transformers Begin to Fail?
Aside from regular maintenance requirements, most operations only pay attention to their transformers once they begin failing. In a perfect world, a new transformer will provide continuous, uninterrupted service for several decades. However, lesser-quality builds often produce much shorter life spans, resulting in power interruptions and unwanted downtime. Initials Signs of Transformer Failure When a […]

How Long Do Dry Type Transformers Last?
Dry type transformers use circulating air to protect the internal components from overheating, unlike oil-filled units that use oil as a cooling medium. Dry type units work exceptionally well for indoor operation because they contain nothing flammable, making them a perfect choice for commercial and industrial applications requiring high fire protection. Generally, if maintenance personnel […]
