6 system requirements of HV and EHV circuit breakers | EEP· It is often necessary to provide such breakers with low ohm breaking resistors, in order to reduce the RRRV. On the other hand, the air blast circuit breakers are less sensitive to the initial transient recovery voltage (ITRV) because of a comparatively high arc voltage.. SF6 breakers are less sensitive to the shape of the TRV because SF6, an electronegative gas, has ions that re-combine ...
