Connecting the system PD-TaD 80
32 / 74 822-188-3
6.4 Ensuring there is no voltage at the work place
Before connecting the test object follow the 5 safety rules:
1. Disconnect the test object.
2. Secure against re-connection.
3. Verify absence of operating voltage.
4. Provide protection against adjacent live parts.
5. Earth and short all phases.
Note:

If the cable sheath is not earthed , establish a short earth connection to the station
earth. The station earth is the neutral point of the earth connections.

The earthing conductor should be as short as possible and show low impedance. Use a
copper earthing conductor with a cross-section of min. 16 mm

.
6.5 Preparing the test object terminals
The test object terminals are the connection point and the far end of the test object.
1. Disconnect all operating resources that are connected to the test object and are not
designed for the stipulated test voltage.
2. Cordon off all metal parts, e.g. lighting masts at the test object terminals or insulate them
with insulating safety plates.
3. Earth all metal parts at the terminals to avoid dangerous charging.
4. All cables that are used in danger zones can also carry high voltage potential outwards.
Therefore, remove these cables from the danger zone or ensure low-resistive earthing
and short-circuit.
5. Follow the cable route and ensure that no work is being carried out underground on gas
lines and that there are no other danger points.
6.6 Setting up the system
PD-TaD 80 integrated in the cable test van

Place the PD-TaD 80 as close to the test object as possible.

Follow the user manual for the cable test van.
PD-TaD 80 as a standalone system

Place the PD-TaD 80 as close to the test object as possible.

Select the place of installation for the VLF HV generator in such a way that

a stable base is guaranteed,

the VLF HV generator is accessible for making connections and for operation, and

sufficient safety distances are maintained. You must comply with EN 50110 for the
operation of electrical installations (EU/EFTA countries) or the relevant standards
applicable in your country.

Set up the Power Box so that the PD-TaD 80, the VLF HV generator and the laptop can
be connected to the Power Box.

Set up the laptop so that you can work comfortably. You could place the laptop on a
transport case, for example.
