Product Description

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
 

1. Latest multiple impulse tech. and impulse balance tech., make the reflected waveform of the fault point obvious and easy to distinguish
2. Adopt high voltage protection tech. to realize the isolation of measuring circuit and the high voltage surging power
3. Simple wiring and matched with generator of other brands
4. No high voltage release

Tech. Specifications
 

Input surge voltage	below 32kV
Input surge current	Below 4000J(instant) and the mean value should below 2000J
Tested impulse voltage	300Vpp
Impulse period	Above 5s
Power	AC 220V,50Hz
Volume	419mm×320mmx341mm
Weight	10kgs
Operating Temperature	-10ºC-40ºC
Humidity	5-90%RH

1. Power port: Working power supply, AC 220V,50Hz
2. Signal port: connect with the pre-locator signal port
3. Power indicator: When power on,the power indicator bright
4. 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.
5. 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 the         two 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.
