A generating plant can not energize longer transmission lines at once after blackout. The generating plant energize shorter transmission lines firstly, then circuit breaker turns on to connect other transmission lines through the transformer. Transient over voltage oscillation may occur in the transmission lines caused by the resonance of the transmission line. It is reported that the peak voltage exceeds more than 2p.u. when the non-sinusoidal wave voltage caused by saturation in the transformer core excites the resonated transmission line.<br>This paper describes the effect for preventing saturation of transformer by turning on contactors with appropriate resistors before main contactors of the 500kV circuit breaker. The first part presents the mechanism of preventing saturation in the transformer core by pre-resistor insertion of 500kV circuit breaker. The second part presents the expected effect in the actual power system simulated by analytical model using a transients simulation program, EMTP.
