6.12 Connecting the HF filter to the PD-TaD 80
The HF filter is used to minimise external influences on the measurement results. We
recommend using the HF filter for all PD tests.
6.12.1 Connecting the HF filter without a connection piece
1. Screw the HF filter onto the
HV IN
connection of the PD-TaD 80.
2. Remove the HV connection clip from the HV connection cable.
3. With a threaded bolt and distance piece, screw the cable lug of the HV connection cable
and an anti-corona hood onto the HF filter.
Ensure that the HV connection cable leads away at a right angle to the HF filter.
6.12.2 Connecting the HF filter with a connection piece
1. Screw the HF filter onto the
HV IN
connection of the PD-TaD 80.
2. Fit the connection piece on the HF filter and screw it on tight.
3. Remove the HV connection clip from the HV connection cable.
4. Attach the cable lug of the HV connection cable and an anti-corona hood to the
connection piece.
The connection piece has a groove to guide the cable lug so that the HV connection
cable is led upwards at an angle of at least 30° to the HF filter.
5. Attach a second anti-corona hood and screw it on tight.
