Abstract

Partial discharge (PD) diagnostics is an important criterion for evaluation of the insulation condition of high voltage electrical equipments. In this paper, Rogowski coil is used as a PD sensor to propose a technique for localization of PD defects based on direction of arrival of PD current pulses approaching towards Rogowski coil. Directional calibration of Rogowski coil is made by analyzing its theoretical and practical response to a PD pulse. An experimental model is presented to implement the proposed technique for straight and branched type power cable network. The proposed technique can be used to increase the accuracy of PD faults localization in an integrated PD monitoring system for a smart electricity distribution network.
