TM10 Cable Outer Sheath Fault Location System
Introduction
The health status of outer sheath is directly related to the safe running of single-core high voltage cable, and intact sheath is the prerequisite to avoid water seepage and failures. If the high voltage cable sheath is damaged, multi-point grounding of the metal sheath and loss of circulation will happen, and the normal safe running of the cable is affected. Thus, it is necessary to take timely treatment for the cable sheath fault. TM10 sheath fault location system can accurately locate cable sheath fault after cable installation, which is the ideal equipment to solve sheath fault.

Features
♦ Three work modes: outer sheath DC withstand voltage test, pin-point signal for generator step voltage method, pre-locate signal generator for resistance (voltage) comparison method.
♦ 2 KV impulse voltage output and big current (200-1000 mA), strong anti-interference capability.
♦ Imported trolley case, easy to carry, strong and durable.
♦ High sensitive amplifier and galvanometer as balance instructor, constituting a balanced bridge with proportional potentiometer bridge.
♦ Bridge using four-terminal resistance test method avoids errors introduced by lead resistance, high precision.
♦ High integration, simple wiring and operation, convenient and easy to find fault location. Users can be skilled after simple training.
