发明名称 Ground-fault protection system.
摘要 1. The ground-fault protection system consists of a Hall transducer, mounted in the air gap of the ferromagnetic core that encloses the cable. The first coil of the Hall transducer is powered, while the second coil of the Hall transducer is connected to the measuring unit. Unique characteristics: The first circuit of the Hall transducer (3) is powered from a zero-sequence voltage source through the phase shifter (5).
