If there is an individual earth leakage protection for the capacitor bank, check its proper operation by pressing the test button. Check that the auxiliary control voltage is within the tolerance limits. If the capacitor bank has an autotransformer, check that it is in good condition and shows no signs of deterioration.
Clean the inside of the cabinet. Clean ventilation grilles. Check that the main switch turns on and of without having to force the mechanism. If there is an individual earth leakage protection for the capacitor bank, check its proper operation by pressing the test button. Check that the auxiliary control voltage is within the tolerance limits.
In making this evaluation, consideration must be given to the sensitivity of capacitor bank protection (such as unbalance protection) and the potential for a capacitor under test to inadvertently discharge stored energy into a protection system. In most cases secondary isolation of the protection system will be required.
The capacitor shall also withstand a 1 minute power frequency withstand test of a test voltage applied between the capacitor terminals and earth. For 12 kV rated capacitors, the test voltage is 75% of 28 kV. Refer to IEC 60871 or AS 2897 for other ratings. The requirements of the test are satisfied if no disruptive discharge occurs.
Measure the capacitance of each individual capacitor unit using a capacitance bridge. The use of any test equipment is to be performed in accordance with the operating instructions specific to the equipment being used. Note that tong type capacitance bridges can normally be used without disconnecting the capacitor units from the bank.
The capacitance measurement should be carried out at a time when the temperature is relatively stable and uniform across the bank. The temperature coefficient for all-film capacitors is approximately -4.5% per 100 degrees C which is significant in the context of out of balance protection.
