Transformer Price List | Electrical Works ...· Distribution transformers and current transformers are found on our electric grid system. Current transformer is a type of transformer used to step down high transmission system current levels to a much lower value and provide a convenient way to safely measure and monitor the electrical current since standard current measuring devices are not configured to measure high current levels.
Glossary of Medium Voltage Switchgear Terms· A device that operates to open all phases of a circuit by means of a polyphase switching device, in response to the interruption of the current in one phase. For example, the striker pin of an expulsion fuse can be used to actuate a common tripping bar which causes a three phase load break switch to open. Index A. Anti-pumping Relay
