I seem not to have access to the professional forums so I post this here:
I understand ohm's law and to get a current you use Volts/Resistance (V/R); so if it's Perspective Fault Current (PFC), it's V/R or Volts/Ze; and we divided by 1000 to convert to kA. Yes?
Is there a difference when calculating PFC on either earthing systems? For a TN-S, TN-C-S, TT or IT, is the same formula used?
Thanks.
