Charge Injection in Gold Ground Electrode Corona Charged Polyethylene Film: Surface Potential Decay and Corona Charging Current Measurement

Charge Injection in Gold Ground Electrode Corona Charged Polyethylene Film: Surface Potential Decay and Corona Charging Current Measurement
Charge Injection in Gold Ground Electrode Corona Charged Polyethylene Film: Surface Potential Decay and Corona Charging Current Measurement
Surface potential decay measurement is a simple and low cost tool to examine electrical properties of insulation materials. Bipolar charge injection has been verified by the measurement of space charge in the corona-charged sample using the pulsed electro-acoustic method (PEA). In this paper, the surface potential decay of gold grounded electrode LDPE sample is compared with the aluminum grounded sample. The decay process observed by PEA and the corona charging result is presented in this paper. It can be clearly seen that the effect of using gold ground electrode is significant, it results in a smaller steady state corona charging current and a slower surface potential decay.

Abstract

Surface potential decay measurement is a simple and low cost tool to examine electrical properties of insulation materials. Bipolar charge injection has been verified by the measurement of space charge in the corona-charged sample using the pulsed electro-acoustic method (PEA). In this paper, the surface potential decay of gold grounded electrode LDPE sample is compared with the aluminum grounded sample. The decay process observed by PEA and the corona charging result is presented in this paper. It can be clearly seen that the effect of using gold ground electrode is significant, it results in a smaller steady state corona charging current and a slower surface potential decay.
