The mutual inductor of electric current and voltage mutual inductor play an important role in relay protection. prevent from ct differential to protect and miss movement an important subject that the generatrix is protected on the saturation, put forward two electric current pass zero hour linear to spread person who become put into differential to protect in ct in recent years, avoid ct saturation district, can judge the bus bar trouble correctly
但是在母線區外發生短路故障（特別是故障電流含有大量非周期分量）時， ct會出現飽和現象， ct飽和后，不能正確地傳變一次側電流，從而使二次電流發生嚴重畸變，產生很大的差電流，這樣就容易引起誤動作。防止ct飽和時差動保護誤動作一直是母線保護的一個重要課題，近年來提出的在ct二次電流過零時的線性傳變區投入差動保護，避開ct飽和區，能對母線故障做出正確判斷。 -
