On-Site Partial Discharge Measurement Using Rogowski Coil for Insulation Condition in MV Power Cables

Dr. Ts. Zaidi Abdullah received a BEng. in Industrial Electronic Engineering from the University Malaysia Perlis (UniMAP) and an MEng. Electrical Power from the Energy University (UNITEN). He recently completed his doctorate focused on using Rogowski coils to measure and detect partial discharges in power cables. Serving as electrical engineer at the Malaysian Public Works Department, he handled more than 25 new projects. Since 2011, he has served as Senior Lecturer at UniMAP, with research interests that include partial discharge measurement, solar PV application and energy management.

On-site partial discharge tools allow early detection before a breakdown occurs in any major part of a distribution system. The two key elements in any on-line partial discharge measurement scheme are the measuring system and the sensors themselves since using the right sensor can significantly enhance PD detection. This presentation reviews research involving on-site PD measurement at substations with 11 kV XLPE power cables to access condition of the insulation based on IEC 60270. It will also explain how characterization of PD in terms of rise time, zero-crossing and resonant frequency was statistically performed in a MATLAB software environment based on real data measured on-line.
