Van Mounted Cable Fault Locating System | ETL-40 High Voltage Cable Fault Locator

ETL40 Van Mounted Cable Fault Locating System

ETL40 Van Mounted Cable Fault Locating System is the most advanced system in power cable fault detection combining the best-in-market technologies into a single fully automatic centralized setup with high reliability and multi-level safety standards. The system is capable of locating faults on low & high voltage cables and pinpointing cable faults of cables with DC voltage up to 40kV.

ETL40 provides high energy of 2000 Joules at every surge level of 8/16/32 kV to enable locate & pinpoint faults on buried power cables, even at long distances or high depth.

FAULT PRE-LOCATION

The ETL-40 Cable Fault locating system is designed for testing & cable fault location depending on fault type and condition, using the following 5 distinct pre-locating modes:

Low Voltage Method:

- TDR Method: low-resistance faults, measuring distance to a high resistance fault, distances to joints, 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, when fault resistance <200Ω

High Voltage Methods:

- ARC Reflection (single/multi shot)- Precise distance to fault measurement creating a flashover at the fault location. Ideal for high-resistance and unstable faults with minimal harmful effects on a cable.

- Impulse Current (ICE) - for those high-resistance faults that cannot be converted to low-resistance by burning faulty insulation.

- Decay Method- Ideal for faults with high breakdown voltage

High energy of 2000 Joules at every surge level of 8/16/32 kV assures that faults can be located on cables up to long distances easily.

Burn Unit

ETL-40 systems are equipped as standard with a burn unit delivering up to 300 mA current at up to 1 A voltage. High-resistance cable faults may be converted to the low-resistance faults by burning faulting insulation, which allows to subsequently apply pre-location and/or pinpointing methods for precise fault localization.

The System is divided into two compartments: operator compartment (OC) and a high-voltage compartment (HC) keeping the operating person safe. Apart from this, the ETL40 is equipped with system self-health and safety monitoring- which are displayed in the centralized control unit screen along with possible resolutions. Visual indicators for Insulation resistance & leakage current present in control unit.

Optional Accessories: 50 watt low frequency surge generator which when used with a locating receiver- can trace cable routes precisely.
