As in a capacitor the voltage always lead the current, the
sum of sending end voltage(reference) added to a voltage of
capacitive line(which is leading) will always gives a
voltage higher than sending voltage. This is the effect
called FERRANTI EFFECT.

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.
