2011-10-20SPECIFICATIONS FOR 132KV OUT DOOR CIRCUIT BREAKERS. A. SYSTEM INFORMATION A-1 System Conditions The networks are mainly of outdoor type. The basic parameters are set out below: Nominal system voltage between phases kV 132 Earthing of neutral at transformers Solid System earthing

The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.

SF 6 gas is extremely stable and inert, and its density is five times that of air. It has high thermal conductivity better than that of air and assists in better cooling current carrying parts. SF 6 gas is strongly

The current transformers shall be of the outdoor type, single phase, 50 C/S, oil immersed, self-cooled, hermetically sealed and suitable for operating in the tropical conditions with maximum ambient temperature up to 500C. The C.Ts should be

2021-3-14Compared with air-blast breakers, operation with SF 6 is quieter and no hot gases are discharged in normal operation. No compressed-air plant is required to maintain blast air pressure. The higher dielectric strength of the gas allows more compact design or a larger interrupting rating for the same relative size as airOperating principle
