Three-phase integrated lightning arrester is a new type lightning arrester which mainly used to protect transformer, switch bus bar, motor, parallel compensating capacitor in 35kV electric system. It also can limit over-voltage of air, vacuum circuit breaker, phase to earth, phase to phase.
Three-phase integrated lighnting arrester consists of four lightning arresters by four-stars type. So, it can protect each phase to earth and phase to phase from over-voltage, because of its smart structure, its function is equal to six lightning arresters, it also solve the problem that lightning arresters can't protect phase to phase very well. Three-phase integrated lighting arrester can be either gap or no gap in series.
