Description
Megger SFX40 Fault Locator Repair
The Megger SFX40 Fault Locator 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.
June Company repairs and calibrates the Megger SFX40 Fault Locator 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.
