These equipments are applicable to the fault test of buried cables below 32KV.It can measure the fault distance, find the cable path and locate fault point. Windows system + touch screen + key operation, all intelligent operation, which can be used by people with or without experience.
I. System purpose:
Accurately and quickly detect the main insulation failure of power cables with voltage levels of 35KV and below; calibrate the cable length; accurately detect the direction and depth of the cable buried.
The system can quickly detect low-resistance, short-circuit, open-circuit and disconnection faults of various types of power cables with different cross-sections and different media, high-frequency coaxial cables, local telephone cables, street lamp cables, and buried wires, as well as high-resistance leakage and high-resistance flashover For permanent main insulation faults and outer sheath faults, calibrate the cable length.
