6v Surge Comparison Tester in coils, windings, electric motors, generators, alternators, and transformers to detect insulation flaws and shorts. Typically, these faults are turn-to-turn, coil-to-coil, or phase-to-phase. It recognises failure at an early enough stage to allow for replacement or repair to be planned during a routine shutdown as opposed to an emergency outage. We pack 6v Surge Comparison Tester in a sturdy material which protects it from any damage while transporting.
