dielectric test is likely to damage the capacitor. The solution is to test with a DC test voltage, at a test potential equal to the peak of specified AC test voltage (1.414 x AC voltage). e) This test requires additional us r precautions and preparation due to high v
iance purposes, it will not pass an AC dielectric. The capacitors to ground (Y caps) will leak excessive current with an AC test voltage, to such an extent that it usually prevents reaching the test voltage – attempting to turn u the voltage will only cause more current to flow. If you are using a production dielectric tester, it w
Most safety standards allow the user to disconnect the Y capacitors prior to testing or, alternatively, to use a dc hipot tester. The dc hipot tester would not indicate the failure of a unit even with high Y capacitors because the Y capacitors see the voltage but don’t pass any current.
In addition, the dielectric voltage withstand test may reveal faults in mechanically damaged insulation or the presence of a foreign material (such as water) which may bridge the insulation. This test is often used after mechanical abuse or temperature tests to confirm that the product has maintained its insulating capabilities.
The majority of safety standards allow the use of either ac or dc voltage for a hipot test. When using ac test voltage, the insulation in question is being stressed most when the voltage is at its peak, i.e., either at the positive or negative peak of the sine wave.
The actual peak voltages from the AC wave are 1.414 times the metered AC RMS value. Thus, the DC test voltage is equal to the highest peak AC voltage. With a DC test, steady-state dielectric current will be much lower because the product’s capacitance is charged only once. This occurs at the beginning of the voltage application.
