Abstract :
The cause and damage of earth potential interference are analyzed and studied in this paper, especially influence by nonuniform distribution of earth potential in power plant and transformer station, such as interference by impulse voltage caused by lightning current and big power frequency current, arc interference caused by earth short circuit in transformer station. On the basis of research on cause, approach and modus of interference, technology measures are proposed.
