Characteristics of Rate of Rise of Restriking Voltage a network consisting of generators, transformers, reactors, and transmission line, each of them exerts its own damping. Usually the attenuation due to them is too small to be relied upon for improvement in the performance of a breaker. Where high RRRV are expected circuit breakers with shunt resistances (Fig. (14.11)) are used.
