In High Voltage (HV) electrical power system the quality of insulation plays an important
role in HV power equipment. Different types of materials like solid, gaseous, liquid and combination of
these material are used for insulation purpose. In HV power equipment most of insulating material are
not perfect in all respect and always contain some impurities. Due to the presence of air-bubbles, voids
are formed within the insulating material. It weakens the insulation region and responsible for partial
discharge and finally the insulation properties of such material enormously degrades its quality. In this
work enameled copper wires are used to study the PDIV and BDV activity. The wires are bend for
different angles and cut into different lengths.
