In electrical systems, capacitor bank testing ensures reliability and performance. It typically measures capacitance, insulating resistance, dielectric, voltage tolerance, and power factor. Implementing IEEE and IEC standards ensures accurate testing & safety compliance.
This test is only applicable when the internal capacitor elements of a unit are separated from its housing. This ensures that the insulation provided between the capacitor parts and the metal enclosure can tolerate overvoltage. The test voltage is applied across the casing and the bushing stand for ten seconds.
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.
In this test, a direct voltage of 4.3 times of rated rms voltage or alternating voltage of 2 times of rated rms voltage is applied to the bushing stands of capacitor unit. The capacitor limit should with stand either of these voltages at least for 10 seconds. The temperature of the unit during test should be maintained at 25 ± 5 Degree.
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.
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. 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.
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.

Damaged capacitor – each capacitor is built with an external casing and if the incorrect capacitor is used, this casing can develop cracks, perhaps through overheating. This can lead to the chemical insulation inside leaking onto the circuit board. This exposes the circuit board to reactive compounds and can have a series of serious knock-on effects.
