Abstract :
Results of power are tests carried out on composite insulators for 110 kV overhead lines are analyzed. The effect of arcing on the basic electrical and mechanical parameters of the tested insulators is examined. Results of pre- and post-arc electric strength tests as well as those of thermomechanical and mechanical tests carried out on insulators subjected to the power arc test are presented
