Product Description XZH TEST Portable cable fault location system is designed for: ★High voltage pulse generator: XHHV535-4Z High voltage 2450J pulse generator is accompanied by a
surge levels switch which allows to achieve the maximum surge
impulse energy at 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: XHGG501B The cable fault tester is
suitable for measuring low resistance, short circuit, open circuit
disconnection faults, as well as high resistance leakage and high
resistance flashover faults in power cables, high frequency coaxial
cables, telephone cables, street lighting cables and buried wires
of various materials with different cross sections and different
media. Superb cable management system with automatic test report
generation. ★ cable fault pinpointer: XHDD503C uses the acoustic-magnetic synchronization principle of
vibration pickup and electromagnetic induction to determine the
specific location of the cable fault point. With the help of a
high-voltage pulse generator, the fault point is flashed and
discharged. The physical phenomena such as vibration waves, sound
waves and electromagnetic waves generated by the flash over discharge of the fault point are collected by the dedicated
probe of the positioning instrument. After intelligent processing
by the host, the fault distance and output fault sound are
displayed. Finally, the precise location of the fault point is
judged by the tester's hearing and vision. That is, the precise
positioning task of the cable fault point "directly above the
cable, within the rough measurement range" is completed. High Voltage Surge Generator XHHV535-4Z Impulse voltage: 0~35kV (default 0~28kV) High voltage partial pressure: 1.5 class Built-in capacitor: 4μF Discharge power: 0~2450 J (default 0~1568 J) Output voltage polarity: negative polarity Impact power: 400W Over temperature protection: 85ºC Working power supply: AC 220V±10% / 50Hz±2Hz Ambient temperature: -20~+50ºC Cable Fault Pre-locator XHGG501B The cable fault pre-locator is suitable for measuring the low resistance, short circuit, open circuit fault, high resistance leakage and high resistance flash over fault of power cables, high frequency coaxial cables, local telephone cables, street lamps and buried wires of various materials with different cross sections and different media. • Industrial 5.7 inch LCD display • Single-chip centralized control, push-button operation mode, strong anti-interference ability; • With ranging, speed measurement, resistance and other functions; • Micro printer and host integration, can print test waveform and test report at any time • Automatic continuous sampling, never miss any discharge waveform • Test method: flash over sampling, low-voltage pulse sampling • Pulse amplitude: 100Vpp • Pulse width: 0.1uS and 2uS • Measuring distance: Smax: 30km Smin: 15m • Measurement error: coarse absolute error: ±10m coarse relative error: ± 1% (DL/T849.1-2004 specifies not more than ±(1%L+20)m, where: L is the cable length) • Power supply: built-in 24V/7Ah DC power supply, can work continuously for 6 hours.
