Portable medium voltage cable fault locating system
Cable fault pre-location: with the reflectometer XHGG502 based on the low-voltage impulse reflection method(TDR), and high-voltage decay (ICE) method DECAY and ARC method. XHDD503C uses acoustic-magnetic synchronization method, equipped with 2048 J surge generator and intelligent digital signal receiver. cable pipe locator: XHLJ507 is an multifunctional equipment, with this equipment, you can realize of cable path tracing, buried depth detection, cable fault point precise location. High voltage 2048 J surge generator XHHV535-4TS is accompanied by a surge levels switch which allows to achieve the maximum surge impulse energy at 8, 16 and 32 kV. It has features operator safety assurance systems and provides a reliable and comprehensive technical solution for low- and medium-voltage cables faults.
