초록
The inductive interference can be happened on some of the communication line that is located near by paralleled transmission line. The causes of inductive interference are magnetic coupling, capacitive coupling and residual voltage at neutral point of transmission line. In this paper, after grounding the one side of communication line, we have measured the voltage to ground at the other side of it. And we also have measured the voltage to ground at the end of it without grounding. As a result, we proved that the cause of inductive interference is the difference of ground voltages.
