| Abstract: | Making use of the theory of the electromagnetic coupling, a two-half-circle current sensor which was used to detect partial discharges pulse current of high frequency from 2MHz to 30MHz in high voltage switchgear based on Rogowski coil was designed. The current sensor has simple structure. It was proved that partial discharges monitoring system based on the current sensor could detect partial discharges of test loop with good sensibility. |
