Product Description XZH TEST Portable cable fault location system includes four parts:1.XHHV535-4Z High voltage surge generator2.XHGG502 ARM Cable fault pre-locator3.XHDD503C Cable fault pinpointer4. XHGX507 Underground cable pipe locator High Voltage Surge Generator XHHV535-4ZHigh 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.Impulse voltage: 0~35kV (default 0~28kV)High voltage partial pressure: 1.5 classBuilt-in capacitor: 4μFDischarge power: 0~2450 J (default 0~1568 J)Output voltage polarity: negative polarityImpact power: 400WOver temperature protection: 85oCWorking power supply: AC 220V±10% / 50Hz±2HzAmbient temperature: -20~+50oC Cable Fault Pre-locator XHGG502The 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. ? The reflected signal sent by the pulse coupler is automatically displayed, and the full-length waveform of the cable open circuit is displayed at the same time.? Automatic calculation and display of fault distance;? It has the function of storing massive test waveforms: the waveforms obtained from the field test can be conveniently stored in the instrument according to the specified order, and can be recalled and observed at any time;? With standard printer USB interface;? Simple operation and high reliability. Has a very high cost performance;? Built-in polymer lithium battery power supply, which can test cable open circuit and low resistance short circuit fault in no power supply environment. Cable Fault Pinpointer XHDD503CXHDD503C 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.Sound channel-Bandwidthl All-pass: 100Hz~1600Hz.l Low pass: 100Hz~300Hz.l High pass: 160Hz~1600Hz.l Band pass: 200Hz~600Hz.Channel adjustment: 8 levels of sound, magnetic and voltage.Sound output: Gain: 16 levels (0-112dB), Impedance: 350ΩDetection range: 0.00-99.99ms, 75mV-75VDetection accuracy: Positioning: ≤0.1m; Path: ≤0.5mWorking power supply: 4*18650 standard lithium battery.Standby time: more than 8 hoursAmbient temperature: -25-65oC; Relative humidity: ≤90%Volume dimensions: 428L×350W×230HOverall weight: 7kgXHGX507 underground cable pipe locator is mainly used for cable fault location, cable identification, cable path and depth measurement. It can complete tasks that could only be accomplished by a few sets of instruments in the past.
