Abstract

Test measurements on a utility power device by a switch matrix apparatus and a common voltage source as separate devices is performed. Through the switch matrix apparatus, the common voltage source 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 switch matrix apparatus from a second terminal of the utility power device. While the first lead and the second lead of the switch matrix apparatus remain electrically coupled to the first and the second terminal of the utility power device, a second high voltage signal is selectively sent via the second lead to the second terminal of the utility power device, and a second corresponding signal returned from the first terminal of the utility power device via the first lead of the switch matrix apparatus is measured.
