Tech. Specifications
Introduction Matched with HVSG-500GN HV generator and PCLC-901D pre-locator to do location of the power cable high resistance leaking fault, flash fault, low resistance fault and break fault. MPC-705 Cable fault multi-impulse coupler is used to offer the multi-impulse signal coupling path for the cable fault locator. It adopts the latest multiple impulse method to simple the judgment of the cable fault waveform. It transfers the complex voltage surging breakdown waveform into the easy distinguished fault waveform. And the requirement to the tech. stuffs is reduced. Along with the low-voltage pulse reflectometry, our systems implement advanced high-voltage pre-location technologies that allow to determine the distance to faults of various types with a minimal harmful effect on the cable lines.High level of safety during the testing with our cable test vans and mobile systems is ensured by built-in protection against overcurrent, overvoltage and overheating, as well as by the use of a continuous grounding monitoring, vehicle door closure sensors and self-health check monitoring. High speed sample system and high bandwidth input circuit are integrated in the tester to get the exact reflection curve of signal so that the distance of fault point to signal sample point can be calculated in high accuracy and high resolution Special sound location tester configuration can be applied to locate the fault point more exactly. The cable fault tester is suitable for measuring power cables, high-frequency coaxial cables, local telephone cables, street lamp cables, low-resistance of short-circuit, open-circuit disconnection faults, and various materials of various materials with different cross-sections and different media. Leakage and high resistance flashover faults. A powerful cable management system that automatically generates test reports. It can test a variety of 35KV under different voltage grade, different sections, different media and all kinds of material of power cable faults, including: open circuit, short circuit, low resistance, high resistance, high resistance leak flashover fault. It can be any cable length measurement of radio wave propagation in the known speed.It can test the power cables buried path and buried depth.route tracing evaluation of electric lines and cables.

Figure2. Operation panel
- Power port: Working power supply, AC 220V,50Hz
- Signal port: connect with the pre-locator signal port
- Power indicator: When power on,the power indicator bright
- High voltage input: Connect with high voltage signal generator,such as our HVSG-500GN generator. Pls notice, the input voltage should no high than 35kV.The impact energy is below 2000J.Otherwise,the device may be destroyed if too high surge voltage and large surge energy.
- High voltage output: Connect the high voltage output line of the target cable. Apply high voltage signal and the multi impulse signal to the target cable. The red clip is negative high voltage output. The black clip is the test grounding.
When high voltage generator work,away from the output clamp.After use,pls release before wire apart.
NOT MISTAKE THE POLARITY OTHERWISE THE DEVICE WILL BE DESTROIED
6.protect grounding: it is the device protect point and must well grounding.
Operation method
- As above fig.3:
- Connect the high voltage output clip with the input of the MPC-705.Then connect the high voltage output line of MPC-705 coupler with the target cable.And connect the ground with the ground grid through grounding line.Make sure well grounding and connect the earth stake with the ground.
- Detailed steps:
- Check the wiring
- Connect the power supply line,turn on and the power indicator is bright
- Change the HVSG-500GN generator into manual mode
- Connect the distance test port of MPC-705 with PCLC-901D cable fault locator
- Start the HVSG-500GN high voltage signal generator
- Adjust the range of PCLC-901D cable fault locator.Before every test,press test key to enter the waiting state
- Adjust the high voltage to the breakdown value,common higher than 5kV.Press HVSG-500GN,manual release and the PCLC-901D cable fault locator will simple and record the multiple impulse then analysis to get the fault distance
- Adjust voltage,range as above until getting ideal waveform
- After use,fully discharge before removing wire.
Notify!!!
- The high voltage device,use need to be strictly comply with the user guide.Make sure the output end to fully discharge after working.Otherwise may bring hurt to the user.
- Device disassembly is forbidden.Part of the inner circuit have high voltage storage,so it might bring hurt to user even when power off.
- If some problem with the machine,pls don't try to modify it.Pls contact us for the solution suggestion.
- The input voltage should be below 30kV.The energy should be below 2000J.Otherwise,maybe some destroys to the device.
Security warming
- The max voltage of the machine is 30kV.Pls caution.
- When the device working,pls keep away from the output clamp!
- Disassemble is forbidden to avoid heavy current shock
