In order to conveniently conduct the study on the electromagnetic compatibility of the low-voltage power line carrier communications with the residual current operated protective device in the laboratory, a testing system was established for the electromagnetic compatibility of the low-voltage power line carrier communications with the residu-al current operated protective device , a testing method as well as a testing program of the electromagnetic compatibili-ty was proposed in this paper for the analog carrier signal being injected into the residual current operated protective device in two kinds of modes---the differential mode and the common mode, and in the end this testing system and testing method turned out to be of great practical values.
