5.2.2.1 Energising with a cable clamp
Individual cables can be energised selectively using a cable
clamp. Unlike galvanic energising, this does not require a direct
connection to the cable and the cable does not need to be ex-
posed.
Energising requires a generator and a cable clamp.
A
NOTICE! Risk of injury from high voltage
If the cable clamp is connected to a single core of a power
cable, high voltages can occur in the cable clamp. These
voltages can lead to shock currents or can destroy the
receiver.
● Only use the cable clamp if you are certain that the cur-
rent in the power cables does not exceed 300 A.
Fig. 23: Arrangement of the devices for energising with a cable clamp
1 cable clamp, 2 generator
With the generator switched off:
1. Connect the cable from the cable clamp to the generator.
2. Attach the cable clamp to the cable to be located.
Follow the operating instructions for the cable clamp.
3. Switch on the generator.
4. Select a suitable power level.
The line is energised with the selected power.
