ELECTROMECHANICAL RELAYS INCLUDING EMBEDDED SENSORS

摘要

An electromechanical protective relay includes a base and an electromechanical coil supported on the base. The relay also includes a load sensor electrically coupled to the electromechanical coil that measures a current passing through the electromechanical coil and that is supported on the base, a trip contact supported on the base and located and configured such that it completes a circuit when the electromechanical coil senses an undesirable condition, and a trip sensor electrically coupled to the trip contact that measures a current passing through the trip contact and that is supported on the base.
