COMPACT CABLE TEST VANETL-15 is a cable test van used for testing cable insulation and locating faults in power cables. ETL-15 is compact enough to be mounted even in a minivan, yet contains all the equipment typically found in a fully-featured cable test and fault location system, including burn module, surge wave generator, time-domain reflectometer and high-voltage DC test module.
Due to its compact composition, ETL-15 can be mounted in most minivans and is therefore an ideal solution for operating in narrow streets of densely built-up areas.
ETL-15 allows to carry out withstand cable acceptance tests with DC (rectified) voltage up to 15 kV.
Detachable time-domain reflectometer RIF-9 included with the system is used for determining the distance to faults in electrical power cables with all the main pre‑location methods:
As standard, ETL-15 includes a burn unit providing capable of outputting up to 1500 mA of current at up to 15 kV voltage.
Fault conditioning through burning faulty cable insulation is used for converting high-resistance faults to low-resistance so that pre-location and/or pinpointing methods could subsequently be used.
A surge wave generator with up to 2000 J surge energy is used for pinpointing cable faults with an acoustic method.
The generator is supplemented with a surge level switch allowing to select output voltage in the ranges of 0…3 / 0…6 / 0…12 kV, which delivers maximum possible energy of the surge pulses.
All-round operator safety systems built into ETL-15 includes the following modules and devices:
✓ Overvoltage and overcurrent protection.
✓ Overheating protection.
✓ Equipment and vehicle chassis protective earthing.
✓ Continuous grounding monitoring system.
✓ Emergency stop button.
✓ Automatic discharge device.
✓ Light and sound indication of high voltage.
✓ Vehicle high-voltage compartment door closure sensors.
✓ Safety ON/OFF keylock switch.
✓ Self-health and safety monitoring of high-voltage switches.
