Study about the Application of Rogowski Coil for measuring Partial Discharge Current

부분방전전류측정을 위한 로고스키코일의 적용에 관한 연구

Rogowski coil is a kind of sensor for high amplitude and very short period current and suitable for the measurement of PD pulse. This paper have simulated the relations between PD signals and Rogowski coil which has its own equivalent circuit and investigated signals of Rogowski coil induced by PD pulse current. and compared with the PD signal obtained from conventional PD measuring system in accordance with IEC60270.
