In case of power plants all emergency loads are connected through UPS. So it is very necessary to keep the Battery in fully charged condition.

However, the battery should be discharged and charged to get maximum life.

It was recommended by Battery manufactures to do the charging and discharge the battery atleast trice in year.

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.
