China AC 220V 50Hz Low Resistance Cable Fault Multi-Impulse Coupler Testing Equipment

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.It can be all kinds of fault testing of railway communication cable, control cable, signal cable of street lamp.
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.
Design Features
MPC-705 Cable fault multi-impulse coupler
Latest multiple impulse tech. and impulse balance tech., make the reflected waveform of the fault point obvious and easy to distinguishAdopt high voltage protection tech. to realize the isolation of measuring circuit and the high voltage surging powerSimple wiring and matched with generator of other brandsNo high voltage release

Power port: Working power supply, AC 220V,50HzSignal port: connect with the pre-locator signal port Power indicator: When power on,the power indicator brightHigh 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 phase-sheath fault, the black clip connected with the sheath and read clip connect with the faulty core. When phase-phase fault, the black clip connect with thetwo faulty cores.
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.
