Abstract
The propagation process of a creepage discharge under a positive impulse voltage application in transformer oil is investigated in detail by means of high speed Schlieren photography and a current measurewent system using LED. In the present work, different sorts of insulating barriers with various thick-ness were placed between a point electrode and a plane electrode. The used voltage is an impulse voltage (1.1/225μs) of magnitude Vm=+30kV.<br>The main results obtained can be summarized as follows:<br>(1) When a simple barrier was inserted between a point electrode and a plane electrode, the discharge figure revealed a barrier type dependence.<br>(2) When barriers were piled up, <br>(i) the current duration, the charge quantity, and the streamer propagation length decreased with the increase of the number of barriers.<br>(ii) most attention should be paid to the barrier facing the point electrode.
