摘要
A second magnetic current transformer (7) controls conductors (L1,L2,L3 ... LN) and makes an electrical conductive connection with a first current transformer (1). A coupling link (8) acting as a high-pass filter fits on a wire path between both current transformers and causes a 180 deg phase angle rotation in the current that passes along the wire path.
