Abstract
A system to determine the ground impedance of a conduit system includes a conductive sheath and a resistor of known value. The conductive sheath is configured to surround a portion of a conductor housed within a conduit system. Capacitive coupling occurs between the sheath and the conductor to establish a voltage source. The resistor is electrically coupled between the voltage source and a metal component of the conduit system, and a voltage drop is read across the resistor to determine the health of the ground impedance of the conduit system.
