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 XHGG502
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. 
• 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 XHDD503C
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.
