As is known to all, uhv ac lightning arrester will be attenuated to varying degrees due to long-term operation on site, including environmental temperature and humidity, breakdown of valve plate and short circuit, leading to uneven capacitor voltage divider, and causing explosion and other dangerous safety accidents in extreme cases. Therefore, it is very important to analyze the electric field potential distribution characteristics of arrester under different operating environment and conditions. In this paper, the equipotential distribution of uhv ac arrester in local damping and local short circuit test is verified theoretically and practically by using fiber optic current method. Based on the field structure and theoretical analysis, the ANSYS 3d theoretical model is constructed to analyze the actual test conditions. The oneness of field test and theoretical calculation shows the accuracy of theoretical calculation.
