Three phase PFC calculator

Calculate PFC

  • Single phase and three phase PFC calculations

Enter any two values to calculate the third.

To calculate the prospective fault current:

  • Enter a voltage value.
  • Enter a Zs or Ze (earth fault loop impedance) value.
  • Calculate.

PSCC single phase = Live to Neutral fault current.
PSCC three phase = Phase to phase fault current.
PEFC = Live to earth fault current.
PFC = The higher of the two values of PSSC and PEFC.

Calculate Zs from PFC

  • Validate your measured Zs or Ze readings.

If you have already measured the PFC, from the PFC measurement you can then calculate what the expected measured Zs value would be.

  • Enter a Voltage value.
  • Enter a PFC value.
  • Calculate.
