pre-defined value always result in a fault detector response. The design, adjustment, and operation of the apparatus must avoid both erroneous functioning and any erroneous nonfunctioning of the fault detector that might be the result of charging currents, imbalance of impedance, or component malfunction.
The proof-voltage test has been used as a manufacturing control test and as an acceptance test to guarantee a minimum level of dielectric defects.
If this test method is used as an acceptance
