WebAn isolator or disconnector, as the name indicates, is a switching or isolation device, intended to disconnect equipment or electrical Circuit from the supply. It is an offload device, which means it can be operated only when the current passing through it is zero. Unlike circuit breakers, it lacks a built-in arc suppression system. Weblevel of isolation now has to withstand the transient voltage between the new building reference potential and its local earth potential. Many transmitters can be destroyed in …
