A sensitive capacitance meter is used to measure the capacitance of the bank as whole to ensure the connection of the bank is as per specification. If the measured value is not as calculated, there must be some wrong connection in the bank which to be rectified. For measuring capacitance of a bank, we need not to apply full rated voltage, instead only 10 % of …
