Addressing window type transformer proximity errors

Abstract

This paper reviews the CT saturation problems associated with mechanical layout complications. The error prediction method is proposed, for the prediction of transformation errors, which is independent of the often very complicated magnetic configurations in which window type CTs are expected to operate. The technique, in fact, predicts a problem that result from the sum of all of interacting field shaping mechanical layout conditions and the particular characteristics of the CT itself and error minimization technique are also presented
