The Megger SWG 1750 series forms the reliable heart of cable fault location systems. It ignites a controlled arc at the fault, generating the travelling waves needed for precise prelocation via ARM or ICE when paired with a Teleflex reflectometer. Operators simply select the lowest effective voltage range then maximise output, ensuring every joule reaches the fault for the loudest acoustic signature. Whether in a compact single-unit version or the two-part 3500 J model, the SWG 1750 handles long cables, wet splices and high-resistance faults with equal ease. For faster, more efficient fault location that cuts excavation costs and downtime, the SWG 1750 is the professional choice.
