2.3.7 Danger during the system’s surge mode
WARNING
Potential differences between the system and the earth
Danger to life or risk of injury due to electric shock.
Potential differences between the system and the earth are possible
during surge mode when the system is positioned on the cable route.
The greatest potential difference and dangerous contact voltage will
occur in the case of a fault due to earth contact in a plastic-insulated low
voltage cable without shielding.
Fault is near the system:
Voltage drops at the fault location. There is risk of electric shock if a
person is standing over the fault location and touches the system
connected to the station earth.
Fault is far away from the system:
As the system is at the same potential as the station earth, there can be
a voltage difference between the system and the neutral earth in the
event of a cable fault, which can lead to rising potential of the station
earth. There is risk of electric shock if a person touches the system
connected to the station earth.
Place the system at a distance of several meters to the cable route
or cable fault location.
When positioning over the cable route, do not use measurement
methods that use a surge voltage and do not isolate the system.
If it is not possible to avoid the hazard by means of a potential increase,
take the following safety measures:
If operating in ‘surge mode’, cordon off the system at distance of at
least 1.5 m.
During surge mode, people may only stand outside the cordoned off
area.
