ABSTRACT:
A system and method for detecting leakage of a part, includes a controller for generating a start command, a voltage generating circuit for generating at least one high voltage pulse signal in response to the start command, at least one testing station including first and second probes for placing a non-conductive part therebetween and for applying the at least one high voltage pulse signal to the non-conductive part, and an inductive detector detecting current from one of the first and second probes. The inductive detector generates a detection signal in response to the detection and transmits it to the controller. The controller compares the detection signal with a reference signal and determines any presence of leaks in the non-conductive parts based on the comparison result.
