Application

The GTJB multiple chopping gap can be used for chopping of lightning impulse voltages between 20 kV and 3600 kV. The chopping can be realized at the front or at the tail of the impulse.

It serves simultaneously as a load capacitor for the impulse generator and allows excellent reproducibility of the chopping time and does not distort the wave shape until the chopping point. It is for indoor operation and mobile design.

Advantages and Features

1.  Automatic adjustment of the sphere distance by the controls
2. Display of the gap distance on the control desk
3. With a manual control box to adjust the gap distance standalone.
4. Usable for some applications as a voltage divider with an additional secondary unit the chopping gap.
5. Equipped with toroid electrodes made of brushed aluminum
6. With wheels at the base frame for easy movement.
