摘要
本文结合了1#发电机单相接地的试验情况,用实际参数论证了采用消弧线圈接地对零序电压的影响,分析了高频衰减振荡谐波和电流表内感对试验结果的影响。
Combining the situation of No. 1 generator＇s single-phase grounding test in our company, this paper demonstratesthe grounding influences by arc suppression coil on the zero sequence voltage, and analyzed that the harmonics of high frequency decay and vibration and the inductive reactance in current meter have impact on the result of the test.
