When a new design of power capacitor is launched by a manufacturer, it to be tested whether the new batch of capacitor comply the standard or not. Design tests or type tests are not performed on individual capacitor rather they are performed on some randomly selected capacitors to ensure compliance of the standard.
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.
Thermal Stability Test. Radio Influence Voltage (RIV) Test. Voltage Decay Test. Short Circuit Discharge Test. This test ensures the withstand capability of insulation used in capacitor unit. Insulation provided on capacitor unit should be capable of withstanding high voltage ensures during transient over voltage condition.
