Abstract
Basic characteristics and applications of magnetic coaxial pipe to current detection are described in this paper. Skin and proximity effect in the pipe with tape-wound structure are discussed. Amorphous tape wound pipe exhibits very good performance for current detection at over several tens of kHz. A new ground fault detector is also developed by using a coaxial pipe in power line. A relay system using the detector breaked the line within 42ms, which is practically enough to protect the power line.
