Abstract

In order to detect and identify correctly acoustics emission（AE） wave of discharge from insulator

the AE of corona is explored systemically by plentiful experiment based on typical rod-plane system.The common test characteristics of AE of corona are summarized based on experiment results.Combining with gas discharge theory and wave theory

the generation mechanisms of corona AE are explained

and then the influence factors of corona AE are analyzed by applying dimensional methods in mechanics.Experiment results show that the AE waves of corona take on regular periodicity and appear once or twice in every test voltage period.Strong and weak AE waves respectively alternately appear in positive and negative test voltage period.In addition

the AE waves are determined uniquely by initial discharge energy E0

which is released instantaneously

under room temperature and standard air press and when rod radius re is much smaller than the gap length.
