Method for testing electromagnetic conduction current method disturbance on wire harness

Abstract

The invention discloses a method for testing electromagnetic conduction current method disturbance on a wire harness, which comprises the following steps of: after a high-frequency current wire harness electromagnetic conduction disturbance test system is built and before the wire harness is tested, carrying out the following tests: enabling a sample to work normally, and respectively carrying out tests at positions 50mm and 750mm away from the sample by adopting a current probe, if the test result is qualified, that is, the test result is more than 6dB lower than the test limit value specified by the test plan, starting to test the wire harness; on the contrary, if the test result is not qualified, the sample and / or the current probe are / is shielded, and then the wire harness is tested. According to the invention, whether electromagnetic conduction current method disturbance on the wire harness meets requirements can be evaluated more accurately.
