Current Transformers

Butler Winding designs and manufactures Current Transformers for a variety current monitoring applications. A Current Transformer is a transformer that is typically designed with the coil wound on a toroidal core. Current transformers may also be designed on a bobbin that uses a split core structure.

Where are Current Transformers found?

• Commonly used in current measuring applications.
• Revenue metering for utility companies.
• Monitoring the operation of a power grid.
• Where there is a need to provide isolation between metering and protection circuits.
• Requirements for safe measurement of large currents, often in the presence of high voltages.
