Product Description
XZH TEST Portable cable fault location system is designed for:
★XHHV535-4TS High voltage 2048 J surge generator 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.
★Cable fault pre-locator: XHGG501A In general, low resistance and open circuit faults (high resistance) can be judged directly by means of an ohm meter or the "pulse method" test waveform of the "cable fault flash tester".
★cable route tracer: XHLJ504L A special instrument for accurately detecting the location of buried cable paths and burial depths within a certain range; Path detection is accomplished by the path signal generator and path signal receiver working in conjunction with the test; through their operation in conjunction with each other, the cable path is precisely located within the approximate cable burial range.
★cable fault pinpointer: XHDD 503 cable fault locator (conventional) is experienced in the use of the acoustic-magnetic
synchronisation principle with double discriminations. It is mainly used for the precise localisation of fault points within the coarse measurement of faults and directly above the faulty cable.
