application s to shunt coil
In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
I Have 3 Phase 10 KW AC Alternator i found one phase weak, so what will be the reason & what action shouls i take to rectify the same.
