ATG 6000 Burn down transformer
ATG 6000 is used for the impedance reduction of cable faults in low and medium-voltage networks. This converts high-resistive, difficult to locate and intermittent faults to low-resistive faults that are easy to locate with the Time Domain Reflectometry method.
Manufacturer: BAUR (Austria).
Description
The short-circuit proof 5750 VA stray field transformer delivers a maximum voltage of DC 15 kV and is contained in a fully enclosed 19” housing. The output voltage can be changed over 8 levels that one can switch to even under load. This allows the output voltage to be adjusted to the respective cable faults. In addition, current and voltage can be limited independently of each other on each level by using potentiometers.
An external ohmmeter that can be connected to the ATG 6000 allows you to determine the fault resistance after a burn process and to evaluate whether additional burning is required.
