The bushing are graded based on the analysis of open and closed circuit breaker tests including supplementary hotcollar ASA., Circuit Breaker Bushings.and C37.401958 Dimensions of Power Circuit Breaker Bushings, so Their Mountings and *UDC 621.3 | 8.57 Bushing Current Transformers 410.

The 1943 U.S.A. standards on apparatus.bushings provide higher test voltages than those specified for circuitbreakers. Un . . TJ ( Outdoor bushing Uu* I Indoor bushing Un On highvoltage circuits (66 kv. and above) bushing current transformers, which are built into the bushings of the circuit breakers (as shown in Figs. 6 and 23 of Chapter VIII), are much cheaper than separate transformers, with their separate Use of these bushings is confined almost exclusively to oilfilled circuit breakers and transformers. The initial objective of the committee was to obtain a standard bushing in each voltage class that would be applicable on either a circuit breaker The bushings are subjected to contamination to perhaps a greater degree than the line insulators, since.they are more In the first place, the switching overvoltages are always greatest at the terminals of the line, either at the circuit breaker
