Underground cable fault locator use in tracing and pinpoint power cable faults

Underground cable fault locator usage tracing and pinpoint power cable faults

System function

• Accurate and rapid detection of the primary insulation cable fault and sheath fault below 220kV, calibrate cable length; accurate detection of cable laying trend and depth.
• System components XHGG series flash cable fault tester, the core part of the whole unit, mainly for the coarse testing of insulation fault in the EHV cable.

• XHDD series cable fault locator is used to pinpoint the main EHV cable insulation failure. XHLJ series cable path analyzer (referred to as: Path instrument) is used to find direction and depth of buried cables.
• High voltage equipment discharge sampler, high voltage test equipment, energy storage capacitors, professional test lines
• Cooperated with flash tester to do coarse testing; with cable fault locator to pinpoint the cable fault point

• Measure the power cable of different sections, different media of various materials, Coaxial cable, Street light cables and short circuit, open circuit short line fault of the low resistivity under ground wire. Superior cable management system, automatically generate test reports.

It consists of three parts as below:
