Different Degree C-Rise Options for Dry Type Transformers
Transformers are electromagnetic devices that change the voltage levels in a circuit. Most dry type transformers contain primary and secondary windings around a magnetic steel core. Power from the incoming voltage source flows through the primary winding, while the secondary winding converts the energy and transmits it to the load. The core supports the windings […]

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 […]

Types of Conductors Used in Dry Type Transformers
Dry type transformers usually contain windings — or coils — that act as conductors. Transformer builds typically have primary windings and secondary windings. The primary windings create input power flow, while the secondary windings convert the power and transmit it to the load through input leads. Transformers with disc windings have conductors wound on the […]

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 […]
