43 Cable testing
43.1 Test voltage
Two possibilities for cable testing are described hereafter.
The following table contains the maximum values for the DC test voltage:
43.2 Safety instructions
Rated voltage of
switchgear [kV]
DC test voltage,
maximum value [kV]
Test duration
[min]
AC test voltage 0.1 Hz,
maximum value [kV]
Test duration
[min]
12 48 15 21 60
24 72 15 42 60
36 72 15 63 60
40.5 72 15 70 60
ATTENTION
Before starting the cable test, the suitability of the cables and cable T-plugs must be ensured
regarding the selected test voltage.
➭ If another test duration than specified above is to be applied, please contact the regiuonal
Siemens representative.
DANGER
High voltage! Danger! Cable testing may produce flashovers which can cause death or serious
bodily injuries.
➭ Cable testing may only be performed by qualified personnel who is familiar with the
danger involved.
➭ The permissible test voltages must not be exceeded.
➭ Keep safety distances.
➭ Install barriers.
➭ Switch on warnings.
ATTENTION
If the voltage transformer is energized, or if it is of the non-disconnectable type, the test
voltage can destroy the voltage transformer and cause personal injuries.
➭ Earth disconnectable voltage transformers before cable testing.
➭ Remove non-disconnectable voltage transformers.
ATTENTION
The voltage indicators CAPDIS-S1+ and CAPDIS-S2+ may be damaged during power-frequency
voltage tests.
➭ Short-circuit voltage indicators with the earthing points of the test sockets.
