Cable Fault Testing and Location

Merqab provides cable fault testing and location services for LV and MV underground cable systems. Our field teams use professional cable fault location equipment — including time-domain reflectometers (TDR), bridge fault locators, surge generators, and acoustic/electromagnetic pinpointing systems — to accurately locate faults in underground cables without the need for excavation across the entire cable route. Cable faults in underground systems can be difficult and time-consuming to locate using traditional methods. Precise fault location minimizes excavation requirements, reduces repair time, and shortens supply interruption periods — all of which translate directly into cost savings and improved service continuity. Merqab's cable fault location teams are experienced across a wide range of cable fault types including conductor faults, insulation faults, sheath faults, and intermittent faults. Detailed fault location reports are provided documenting the test methods used, fault distance measurements, and pinpoint results.
