Operation
40 Cable testing
40.1 Safety instructions
40.2 Test voltage
Two possibilities for cable testing are described hereafter.
Test voltages
DANGER
Life-endangering high voltage
Can cause death, serious injury and property damage. DC voltage applied to the cable
and overvoltages at the busbar can cause flashover.
➭ Keep safety distances.
➭ Install barriers.
➭ Switch on warnings.
DANGER
High voltage and explosion hazard
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.
➭ Switch disconnectable voltage transformers to EARTHED position before testing the cables,
and secure them.
➭ Remove non-disconnectable voltage transformers.
NOTICE
Voltage indicators may be damaged by test voltage during cable tests.
May cause property damage.
➭ Short-circuit the voltage indicators with short-circuit plugs at the earthing points of
the test sockets.
