Data record instr.cable-fault-locator.pinpointing

Verified 2026-10-27 Confidence: Medium

Pinpointing takes place on the ground above the cable route while a surge generator (thumper) discharges into the cable repeatedly and causes a flashover at the fault; a ground microphone and an electromagnetic pickup detect the signals, and the fault lies where the time difference between the electromagnetic impulse and the slower acoustic signal is smallest.
