摘要: Intermittent earth faults occur frequently in urban distribution networks, causing overvoltage the whole system. This paper first presents characteristics of transient caused by intermittent faults. Overvoltage level at end a sound line turns to be higher than that faulted line. In resonant grounding system with Petersen coil based on thyristor controlled reactor (TCR), appears more severe due response delay compensation. Therefore, influence compensation is analyzed, which, an suppression method proposed.
