Abstract :
One of the main tests of power circuit breaker is to evaluate their breaking capability. Direct test requires a high power source capacity but using the synthetic method and supplying current and voltage from two separated sources, allows to significant power reduction. This paper presents the design, development and fabrication of a synthetic circuit for testing vacuum circuit breaker using distribution network as current circuit. The development and construction of this equipment has made possible to perform short circuit breaking test on VCB according to international standards. Laboratory measurements show good conformity between design and fabrication.
