METHOD AND APPARATUS FOR TESTING UTILITY POWER DEVICES

摘要

An apparatus for performing measurements on a utility power device that shares a common ground with the apparatus selectively sends a first high voltage signal via a first lead to a first terminal of the utility power device, measures a first corresponding signal returned via a second lead of the apparatus from a second terminal of the utility power device. While the corresponding first lead and the second lead of the apparatus remain electrically coupled to the corresponding first and the second terminal of the utility power device. The apparatus selectively sends a second high voltage signal via the second lead to the second terminal of the utility power device, and measures a second corresponding signal returned via the first lead of the apparatus from the first terminal of the utility power device.
