APPARATUS AND METHOD FOR SPARK FAULT DETECTION AND TYPING

摘要

A spark fault tester apparatus includes an electrode; a power supply operatively connected to provide an electrical field at the electrode; a voltage monitoring module operatively connected to measure the intensity of the electrical field at the electrode; a current monitoring module operatively connected to measure a current output of the power supply; and a microprocessor operatively connected to sample the voltage monitoring module and the current monitoring module, and to adjust the power supply. The microprocessor implements a voltage regulation algorithm and a fault typing algorithm, based on samples of the voltage and current monitoring modules, to distinguish among at least two types of insulation defects.
