Surge protective devices (SPDs) are applied in the low-voltage AC power system to limit lightning transient overvoltage so as to protect the low-voltage electronic devices. However, traditional SPDs have some shortcomings such as too many components that are big in size. Aiming to overcome these shortcomings, a simplified circuit is proposed when the circuit of traditional SPD is analyzed in this paper. Simulation analysis of the lightning transient response of traditional and simplified circuit is performed with PSCAD/EMTDC, and furthermore, the simulation results of two circuits are compared. It shows that the simplified circuit has a qualified protective performance and can be applied to lightning overvoltage protection of electronic devices in low-voltage AC power system by comparison.
