摘要

An abnormality occurring in a ZCT is detected simply and reliably. A zero-phase-sequence current transformer (ZCT) (11) detects zero-phase-sequence current in power wires inserted therethrough, and in addition to the power wires, has inserted therethrough a wire through which a constant DC offset current flows.
