Floating electronic equipment electric rapid transient pulse group protection method

The invention provides a floating electronic equipment electric rapid transient pulse group protection method. One end, close to a grounding panel, of floating electronic equipment is provided with artificial ground. Firstly, a device to be tested, an EFT generator, a socket, and leads are successively connected on an experiment table; secondly, the EFT generator is set to test the device to be tested; thirdly, a 'start' button is started to carry out EFT noise immunity test, if the device to be tested works normally, the test is finished, and if the device to be tested works abnormally, the EFT protection is carried out; and fourthly, the bottom of the casing of the device to be tested is additionally provided with a piece of artificial ground tightly attached to the bottom of the casing of the device to be tested, and the EFT noise immunity test is carried out again. The protection method can effectively avoid EFT interference.
