ETL-15

COMPACT CABLE TEST VAN

ETL-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.

FITS IN THE SMALLEST VEHICLES

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.

DC WITHSTAND TESTING

ETL-15 allows to carry out withstand cable acceptance tests with DC (rectified) voltage up to 15 kV.

FAULT PRE-LOCATION

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:

Low-voltage method

  • TDR (time-domain reflectometry): low-resistance faults, open cable breaks, various impedance changes characterization (cable sleeves, branches, etc.), total cable length measurement (incl. on a drum or bundle) and cable shortening ratio measurement.

High-voltage methods

  • ARC/ARC multi-shot (arc reflection method): high-resistance and unstable faults, minimal harmful effects on a cable.
  • ICE (impulse current envelope method): high-resistance faults that cannot be converted to low-resistance by burning faulty insulation.
  • DECAY (voltage wave oscillation method): faults with high breakdown voltage.

HIGH-POWER BURN UNIT

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.

SURGE WAVE GENERATOR WITH A SURGE LEVELS SWITCH

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.
