ATG 2 burn down transformer

The ATG 2 burn down transformer 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.
The short-circuit proof 2300 VA stray field transformer delivers a maximum voltage of DC 10 kV and is contained in a fully enclosed 19” housing. The output voltage can be changed across 6 levels that can be switched 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 2 allows you to determine
