Partial Discharge Analysis of Bio Degradable Nano Filled Oil Under Different Electrode Geometry

Abundant insulation between different active parts of the transformer is mandatory for its prudent operation. Nano filled bio degradable oil is used as an insulating medium as an alternative for mineral oil in a transformer. Electrical discharges known as partial discharges (PDs) take place in the transformers' insulating system. Transformer insulation system stagnation is caused by the PDs phenomenon. To prevent the transformer from completely breaking down, it is vital to calculate and detect the PD at a primary stage. The PDIV and PD characteristic of Nano-filled biodegradable oil were discussed, and tests were carried out using electrode configurations with needle plane and rod plane. With the oil in the test cell, PDIV and PD activities of Nano filled biodegradable oil were compared and studied. The impact of oil condition on PDIV and PD features was taken into account. The maximum electric field stress is shown by changes in electrode arrangement, and conversely, the measured PDIV value is shown to be the lowest.
