A capacitor must survive a 10-second DC test voltage supplied between its primary terminals. UTest = Un x 4.3 x 0.75. U Test represents the applied test voltage. U n stands for the capacitor’s rated voltage. The capacitor must also pass a one-minute power frequency withstand test with a test voltage applied across the capacitor terminals & earth.
To avoid damage caused by applying high voltages to capacitors, the test voltage should have a substantial margin to VBR, and using test voltages equal to 50% of the first percentile of the VBR distributions seems to be reasonable and consistent with literature data [6-7].
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.
Design tests and type tests are typically expensive or damaging. The type tests performed on the capacitor bank are: High Voltage Impulse Withstand Test. Bushing Test. Thermal Stability Test. Radio Influence Voltage (RIV) test. Voltage Decay Tests. Short Circuit Discharge Test.
Typically for low voltage capacitors the dielectric withstanding voltage test is carried out at 2.5 times the rated voltage. Based on parameters of the relevant distributions the probability of failure during this test, P2.5, can be calculated.
As a general rule, a properly designed capacitor of sound construction should withstand the normal 25°C dielectric withstanding flash voltage even when the temperature is 125 ° C.
