Does this mean that all ungrounded systems will need a voltage based protection for safety of personnel, if the damaged part, say for instance HV cable on a cable ladder is accessible to personnel?
Hi all,
I a trying to understand how it is that the HV cable can withstand the VLF hipot testing.
I thought that when a cable insulation is rated for a voltage, say 6.35/11kV, then the cable cannot be subject to voltages above 6.35kV ph-E and subjecting it to higher voltages would result in...
