Abstract：Cascaded surge protective devices (SPDs) are chosen to protect sensitive equipment against surge current in electrical and electronic system in the threat of overvoltage caused by lighting.The two-stage cascaded voltage-limiting SPD is a common form and its main voltage-limiting element is the metal oxide varistor (MOV).Subsequent lightning return stroke occurred in natural lightning flashes not only rises very steeply,but also will affect the V-I characteristics of the MOV and the energy coordination of the two stages.Experiments were carried out in this paper to test the V-I characteristics of the MOV under subsequent lightning return stroke.Based on the characteristic changes of the MOV residual voltage,theoretical analysis was carried out on the SPD coordination under subsequent lightning return stroke.The further simulation considered the influences of the SPD coordination under subsequent lightning return stroke,and the experiments were carried out to verify the simulation results.The simulation and experimental results show that the residual voltages of the MOV under subsequent lightning return stroke increase about 6.8%～36.8% compared with which under 8/20 μs impulse current.The subsequent lightning return stroke makes the cascaded SPDs reach better coordination,but also may cause the malfunction of SPD2 and lose protection capacity accordingly.Meanwhile,the SPD combinations,the distance between cascaded SPDs and the type of load also affect the coordination of SPDs under subsequent lightning return stroke.
