The invention discloses a trip pressure plate detection tool based on electromagnetic pulse induction, which comprises an annular shell, wherein the upper surface of the shell is provided with an annular shell cover, a shielding layer is arranged close to the inner surface of the shell, a circuit board for inducing pulse voltage is arranged in the shielding layer, the circuit board mainly comprises a signal receiver, a signal processing circuit, a digital processor and a power supply which are sequentially connected, and the shell cover is provided with a signal indicating lamp connected withthe digital processor, a reset button, and a power switch connected with a power supply. The tool has the advantages of simple structure and flexible application and can achieve the detection of the tripping pulse on the tripping pressure plate of a relay protection device by directly covering the pressure plate pile head with the tool in a non-contact electromagnetic pulse induction mode, the potential safety hazard of detecting the trip pressure plate is greatly reduced, and the safety performance is good.
