摘要（英）：

The invention discloses a testing system and method for simulating the increase of a transient ground potential, and the testing system comprises a controller MCP, a high-voltage DC power supply HVCD, a capacitor C1, a high-frequency inductor L1, a current-limiting resistor R1, a gas switch K1, a gas switch K2, a current-limiting resistor R2, a wave regulating circuit LR, and a simulation grounding platform SGP. The simulation grounding platform SGP is grounded through the high-frequency inductor L1, and the high-voltage DC power supply HVCD is connected with the capacitor C1 through the current-limiting resistor R1. The gas switch K1 can enable the capacitor C1, the wave regulating circuit LR and the high-frequency inductor L1 to be connected, and the gas switch K2 can enable the capacitor C1, the wave regulating circuit LR, the high-frequency inductor L1 and the current-limiting resistor R2 to be connected. Through different grounding impedance changes, the system can achieve the simulation of the increase phenomena of a grounding network at different stages through employing a controller to control the on/off of different gas switches.
