Abstract

PURPOSE: To provide a method of measuring individual grounding resistance in common grounding system for distribution lines, according to which split type transformer is attached to grounding line. power source voltage of an appropriate frequency is injected into the grounding line, and current passing through the grounding line is measured, whereby individual grounding resistance can be measured simply and with an accuracy practically required, without removing individual grounding lines.
