Detection and position location of partial discharge in transformer oil / Muhammad Sufi Ahmad Bukhari

Power transformers are one of the most important and most expensive components in the electric power system. Therefore a huge interest for monitoring and diagnosis systems to evaluate the condition of the transformer is necessary to analyse the actual status of the insulation system. Acoustic detection is one of the methods to detect partial discharge (PD) of the insulation of the power equipment. The primary advantage of Acoustic detection is that position information is readily available from acoustic systems using sensors at multiple locations. This position information can help to identify the type of partial discharge as well as the location and severity of an insulation fault. The position information can also help plant technicians locate faults in insulation for repair purposes. Therefore in this paper, acoustic detection method will be use to detect and locate partial discharge in transformer oil using MATLAB software to simulate the partial discharge activity in transformer oil. Results showed that the method employed is suitable and can provide for correct location of partial discharge in transformer oil.
