Abstract: Partial Discharge (PD) monitoring of cables under high voltage stress plays an important role in monitoring cable insulation quality and preventing insulation breakdown. Cables in distribution and transmission networks are therefore subjected to continuous monitoring methods to check on the level of High Voltage (HV) equipment insulation’s degradation, the results are used to predict the insulation lifespan and to plan out schedules of phasing out of equipment with insufficient insulation quality. PD detection devices are usual powered up by electricity from the grid or using batteries that needs to be continually charged. This begs the question whether we can power up the devices through alternative methods to decrease the amount of maintenance that needs to be done. The Final Year Project seeks to investigate whether it is possible to generate sufficient energy under constant power condition to power up a Partial Discharge detection device through the electromagnetic induction from magnetic fields produced from current flowing through XLPE cables under high current conditions in 230kV substations. This report will include topics such as PD detection devices, materials that could be used to power up the devices, and improvement on the circuit to provide constant voltage to the PD devices under fluctuating conditions. Through reading this report, the reader can gain some insights on generating electricity from electromagnetic induction and how to constant voltage levels are maintained to drive the PD devices.
