Abstract: In high voltage electrical power system, variety of solid, liquid and gaseous materials are used for insulation purpose to protect the incipient failure inside the power equipment. Among these the solid insulation is widely used for high voltage power equipment in electrical power system. Most of insulating materials are not perfect in all respect and contains always some impurities. The presence of air bubble (void) is one of such impurities in insulating materials and highly undesirable for such type of insulation which causes a local weak zone inside the insulator. Insulation of the power equipment gradually degrades inside the insulator due to collective effect of electrical, chemical and thermal stress. Due to the high voltage stress the weak zone inside the insulator causes the partial discharge (PD) which is known as local electrical breakdown. As a result the insulation properties of such materials are enormously degrades its quality due to the PD. In this work, the simulation of PD activity due to presence of a small cylindrical and cubical void inside the solid insulation material of high voltage power equipment is studied with the MATLAB Simu link platform.
Keywords: Electrical insulation, cylindrical void, partial discharge, high voltage equipment.
