Abstract

There is an increasing demand for metal-clad switchgear for use on power systems rated up to 38 kV. This paper addresses some of the design problems, and solutions to those problems, encountered in designing and testing a 38 kV vacuum circuit breaker and associated metal-clad switchgear. Subjects covered include ratings, the effect of two differing sets of standards (ANSI and IEC), vacuum interrupter selection, testing procedures, and designing to control electrical stresses
