Abstract: An electrical part testing system for evaluating quality of an insulated electrical part, including a computer-controlled switching apparatus for providing an original voltage to the electrical part automatically according to a pre-established testing scheme calling for provision of voltage to each phase of the part, in turn, while grounding the other phases of the part. A high-frequency filter for receiving receive the original voltage, receiving a load voltage emanating from the electrical part in response to the part receiving the original voltage, and filtering the original voltage from the load voltage to isolate any partial-discharge voltage added to the original voltage by the electrical part while the part is being electrified by the original voltage, yielding a filtered signal. A computing device determines, based on a comparison of a peak amplitude of the partial-discharge inception voltage to a voltage threshold, the quality of the electrical part being tested.
