| 漏电电流和 零序 电流区别 Difference between Leakage Current and Zero Sequence Current 零序电流产生条件:三相负载不平衡、接地故障、相间 短路 电流均会产生零序电流。 Zero sequence current generation conditions: unbalanced three-phase load, grounding fault, short circuit current between phases will produce zero sequence current. 漏电流产生条件:接地故障。 Leakage current condition: ground fault. 根据保护三个特性: According to three characteristics of protection: 选择性、快速性、可靠性。 Selectivity, rapidity and reliability. 零序电流保护，零序电流接地和相间短路情况下保护动作，但是三相负载不平衡情况下也能跳闸，误跳情况。漏电流保护，出现接地故障可靠动作。 Zero-sequence current protection, zero-sequence current grounding and inter-phase short circuit protection action, but three-phase load imbalance can also tripping, false tripping situation. Leakage current protection, reliable operation of grounding fault. 综上所述，针对接地故障情况，只有漏电保护才能可靠动作。 In summary, for grounding fault, only leakage protection can operate reliably. |
