Abstract

By comparison and analysis of the original equivalence magnetic field and circuit of the zero sequence CT for electric leakage protection with which with a electromagnetic shield, this paper shows how the electromagnetic shield works, finds that the CT with electromagnetic shield is with different characteristics from the original one. It is concluded that the electric leakage protection will not pickup when certain fault occurs.
