摘      要：When designing high-voltage elements,knowing if the corona effect will be present during their life cycle is ***,designers consider several prediction criteria based on physical features related to breakdown discharge principles to predict the corona *** introduced practical set-up consists of a concave cone electrode with a hemispheric tip above a plate to evaluate selected corona prediction *** hemisphere has a fixed diameter of 7 mm,and the electrode separation ranges from 2.5 to 39 *** about the corona mode inception under different voltage sources was extracted using an intensified charge-coupled device camera and a partial discharge *** prediction criteria were connected to a specific corona mode depending on the main discharge structure behind its *** average deviation between these criteria and experimental results was around eight *** assumptions in criteria are also discussed in light of the experimental results.
