Data record instr.cable-fault-locator.sheath-fault-location

Verified 2026-10-27 Confidence: High

A failed sheath test on a direct-buried cable is followed by sheath fault location by the step voltage (ground gradient) method: the fault locator serves as a pulsed high-voltage source, and a separate receiver reads the strength and polarity of the ground gradient voltage, which rises when the fault is approached, falls to zero directly over it and reverses polarity beyond it.
