Summary:
This paper identifies and explores the different methodologies in detection of voids and signs of corrosion in the 750V DC XLPE cable insulation that causes partial discharge (PD), as well as analyzing its transient behaviour using MATLAB simulation. MATLAB software is used to study the partial discharge behaviour and their voltage waveforms with respect to the magnetic field. This allows better understanding of the occurrence of partial discharges and methods that can be used to predict future cable failures. Based on the Partial Discharge behaviour simulated by software and correlation with experimental results from Non-Destructive thermographic imaging of intentional generated defects in XLPE cables, it allows identification of voids and potential corroded cable. The work allows early detection of flaws, preventing potential cable failure and provide timely maintenance
