Abstract
Based on the electromagnetic coupling method, a new kind of clamp current sensor was designed to detect partial discharges (PD) in XLPE cable joint. The sensor is a Rogowski coil with a non-crystal core, its bandwidth is located in very high frequency band (VHF) from 1 MHz to 60 MHz. Our test results both in our laboratory and on-site measurement indicated that the sensor is suitable for PD on-site testing and on-line monitoring in XLPE cable joint.
