Autor: Koichiro Ninohei, Fumio Iwasaki, Masayuki Ibe, Seiichiro Okamura

Publikováno v: IEEJ Transactions on Power and Energy. 126:51-58

ZCT (Zero-phase-sequence Current Transformer) is used widely for the detection of the ground fault current in low or high voltage distribution power line. Especially, the use of pole air switches equipped with ZCT is increasing to prevent the extende

The Measuring and Protection Method for the Abnormal Rise of Magnetizing Inrush Current in a Divided Type 3 CTs System

Autor: Fumio Iwasaki, Masayuki Ibe, Seichiro Okamura, Koichiro Ninohei

Publikováno v: IEEJ Transactions on Power and Energy. 125:899-906

This paper describes the measuring and protection method for the abnormal rise of magnetizing inrush current in a divided type 3 CTs system. By divided type 3 CTs system, it is possible to measure the primary phase current and zero phase current at t
