Abstract

PURPOSE:To obtain an economic breaker equivalent testing circuit by using an insulator type gas breaker which is readily strengthened in ground insulation. CONSTITUTION:An auxiliary breaker which, together with a multibreak ground type gas breaker for testing, breaks a large current form a power circuit, providing an approximately equal arc time, is supported by supporting insulator tubs 14... attached to a base 15 and forms an insulator type gas breakers in which breaking units 12 each connected with a capacitor 13 in parallel are connected together in series. Using this auxiliary breaker which is readily insulated from the ground permits an economic breaker equivalent testing circuit to be obtained.
