Description
Megger TDM45 Diagnostic Tester Repair
The Megger TDM45 Diagnostic Tester is a cable fault locator – it finds where a cable has failed, usually by combining a surge generator that makes the fault arc with a receiver that pinpoints it. Two very different subsystems, and they fail independently.
Certified technicians at June Company service the Megger TDM45 Diagnostic Tester for utility cable crews, electrical contractors, and underground distribution teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
