종속 접속된 전압 제한형 SPD의 에너지 분담 해석

초록

It is important to obtain an acceptable energy sharing in coordinated Surge Protective Device(SPD) system. this paper presents the experimental results of energy coordination between ClassⅠ tested SPD and ClassⅡ tested SPD in 10/350 ㎲ impulse current. As a consequence, the energy between cascaded SPDs is depending on the voltage protection level, the distance between two SPDs and current waveforms. It was found that the rate of energy sharing between cascaded SPDs in 10/350 ㎲ impulse current does not match with that current sharing.
