CABLE TEST VAN
ETL-40 is a fully equipped van-mounted cable test and fault location system which allows to:
The entire system is controlled from a central operator station. Microprocessor based operation ensures high measurement accuracy and reliability of the test results.
ETL-40 cable test van allows to carry out cable acceptance tests with high DC voltage up to 40 kV.
Time-domain reflectometer RIF-9, integrated into the ETL-40 control panel, is used for detecting and determining the distance to various types of faults in electrical power cables with the main pre‑location methods:
As standard ETL-40 systems are equipped with a burn unit which delivers current up to 1 A at up to 20 kV voltage.
High-resistance cable faults may be converted to the low-resistance onces by burning faulty insulation which allows to subsequently apply pre-location and/or pinpointing methods for precise fault localisation.
A surge wave generator with up to 2000 J surge energy is used in ETL-40 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 … 8 / 16 / 32 kV, which delivers maximum possible energy of the surge pulses.
ETL-40 is designed to fit into the majority of the popular vehicles.
The compact composition of the modules making the system up allows it to be mounted even in short wheel base vans.
All cable test vans of ETL family are equipped with all-round operator safety systems consisting of the following modules and devices:
