Also, measure and verify if the supply voltage, phase currents, and the kVAR of the capacitor bank are within the allowed limits. Approximately 8 h after energization, conduct a visual inspection of the bank for blown fuses, bulged units, and proper balance in the currents.
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.
ANSI, IEEE, NEMA or IEC standard is used for testing a power capacitor bank.There are three types of test performed on capacitor banks. They are Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests.
This results in a decrease in the power factor of your system. Eventually, this leads to power factor loss. Therefore, it is essential to regularly test the capacitor bank and ensure its reliability and performance. A capacitor bank is static equipment.
For P.F Correction The following power factor correction chart can be used to easily find the right size of capacitor bank for desired power factor improvement. For example, if you need to improve the existing power factor from 0.6 to 0.98, just look at the multiplier for both figures in the table which is 1.030.
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
