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.
This test is performed on each capacitor unit to demonstrate, the loss occurs in the unit during operation is less than the maximum allowable loss of the unit. In this test the capacitor unit is first charged with direct voltage (DC) up to 1.7 times of the rated rms voltage of the capacitor unit.
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.
Why Test Capacitors Longevity: Testing helps detect early degradation, extending capacitor and device lifespan. Performance: Confirms capacitors are working efficiently, crucial for electronic circuit stability. Safety: Identifies faults that could lead to electrical hazards, protecting equipment and users.
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.
The voltage once calculated or estimated and applied, it must be maintained with in ± 2 % though out 24 hours of the test period. This test is done at rated frequency and 115 % of rated rms voltage of capacitor. This test is only performed on the unit having more than one bushing.
