Why Do Transformers Hum? Understanding Transformer Noise
Loud equipment is often a nuisance, but it can also be a safety issue if it contributes to excessive noise levels. Transformers often hum or buzz, but it usually doesn’t mean anything is wrong with them. Humming can be a sign of normal operations and magnetic forces at work. Still, too much transformer noise can […]

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 […]

C-Rise Insulation Options for Dry Type Transformers
Because transformers convert power into higher or lower voltages, they generate heat as a byproduct. This heat causes increased temperatures in the transformer’s internal components, including the primary and secondary windings. A transformer’s temperature rise — or C-rise — is the average temperature of the windings in Celsius over the surrounding temperature when the transformer […]

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 […]
