Experimental investigations on remote measurement of HV electrode current

Abstract

Low Density Polyethylene(LDPE) is considered as an important material for the insulation in high voltage dc.The knowledge of conduction current and in LDPE material is quite vital due to the fact that it is related to charge accumulation in it.Tounderstand the whole information of conduction current and space charge accumulation, we have been trying to construct a new method wherethe measurements are performed using a guarded three-terminal electrode system.Traditionally, the measurement of conduction current was done on the ground electrode due to safety reasons. With the advent of wireless technology such as Zigbee modules etc, the measurement at high voltage electrode is also possible. So by taking dielectric sample as LDPE, we have been trying to find the conduction current and space charge accumulated in it.
