A 2-MV 4.5-MJ Synthetic Test Source for HV Circuit Breakers

This paper describes IREQ´s synthetic test source, which underwent commissioning tests in July 1983. Its unusual physical and electrical characteristics are given along with a description of its fully computerized operation. This source has already been used for six different types of test. Tests on full poles of 735-kV circuit breakers as well as on metal-oxide surge arrester sections intended for a 735-kV transmission system were performed.
