Internally Mounted Dry-Type Bushing Current Transformer

Our internally mounted Dry-Type Bushing Current Transformer is designed to be mounted onto the high-voltage bushing of a dead tank power circuit breaker, along the ground collar, protected by an external cover. When installed in combination with air insulation, it can provide a higher voltage level dielectric system. Its precision construction provides low leakage with extremely high short circuit capabilities. When a multi-ratio winding arrangement is required it is wound in a manner that assures a fully distributed winding between any connection. The coil is finish insulated with a double wrapping of polyester film. The insulation system is rated 600 volt class dielectrically and 105 degrees centigrade thermally.
