Electromagnetic pulse protection device performance test method and device

The invention discloses a method for testing an electromagnetic pulse protection device, which is characterized in that the protection device is connected in parallel with a nonlinear element between a protected circuit and the ground to discharge pulse current to the ground, a pulse source is connected to a cable input end of the protection device, and pulses are input between a cable and a ground wire; a resistive load is arranged at the cable output end of the protection device, the resistive load is connected between a cable wire for pulse injection and a ground wire, and pulse signals are tested at the two ends of the resistive load. The invention also comprises an electromagnetic pulse protection device test system for realizing the method. The invention designs a performance test suitable for verifying a single electromagnetic pulse protection device before equipment is installed, so as to solve the problem that an electromagnetic pulse protection device product cannot be directly verified. 本申请公开了一种电磁脉
