Characteristics and Change of Electrode Surface in Moisture Absorption on the Series Gap Surge Arrester
직렬 갭 피뢰기의 흡습시 전극표면의 변화 및 특성
Abstract
The characteristics and change of electrode surface about Gap type surge arrester for protect DC subway rail were investigated with moisture absorption. Compared that tested about DC/AC discharge commencement voltage, residual voltage, Impulse, square wave impulse for DC rail surge arrester about Gap type surge arrester of moisture absorption state. The AC discharge commencement voltage acted greatly effect of moisture absorption than the DC discharge commencement voltage test.
