Ukraine, CIS [UA] Van-based cable test and fault location system ETL-8 is used for testing cable insulation and locating cable faults using a variety of methods.
Due to its compact size, ETL-8 may be installed in a minivan, yet it is a fully‑featured cable test and fault location system which incorporates burn module and surge wave generator, and is capable of faults pre‑location and cable insulation testing with high DC voltage.
FITS INTO COMPACT VEHICLES
ETL-8 can fit into most minivans, which is an ideal solution for cable fault location in dense urban areas and on narrow streets.
DC TESTING
ETL-8 system allows to carry out cable acceptance tests with DC (rectified) high voltage up to 8 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
High-voltage methods
BURN UNIT
ETL-8 is supplied with burn unit as standard which delivers current of up to 100 mA at up to 8 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 1000 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…2 / 0…4 / 0…8 kV, which delivers maximum possible energy of the surge pulses.
SAFETY
All-round operator safety systems built into ETL-8 includes the following modules and devices:
