Filed: 1989-11-29
Abstract: PURPOSE:To measure partial discharging pulses with a high SN ratio and high sensitivity by providing a coil outside the cable which is shielded with a wire shield and measuring the partial discharging pulses by the electromagnetic coupling between the wire shield and the coil.
