Abstract

After analyzing the UV imaging method applied to corona discharge detection in electric power device and its influencing factors

an experimental research is taken on test field in a 1 000 kV substation.The experimental results show that the test distance

gain and environmental humidity have great influence on UV imaging test results.The relationship between these main influence factors and the photon counting rate verify the theoretical analysis.Field application of UV imaging instrument and evaluation of UV imaging test data can benefit due to the experimental research.
