Abstract : To investigate the Partial Discharge (PD) inside the solid insulation a MATLAB based Simulink model has been developed in this work. The fuzzy classification technique has been used for the classification of apparent charge due to PD activity. The model is used to study the effect of applied voltage, different void sizes and different insulation materials on Partial Discharge. It is found that with the increase in applied voltage and void size there is significant increase in the apparent charge. Also apparent charge changes with the different insulating materials. It establishes the fact that Partial Discharge activity in insulation highly depends upon certain factors like applied voltage, size of the void and dielectric constant of insulation material. © JES 2013.
