FAQ's & How to
How to calculate PFC
To calculate PFC
- Enter a Uo Voltage value.
- Enter a Ze or Zs value.
- Tap Calculate.
Uo = Line to Earth Voltage
Zs = Circuit Earth Fault Loop Impedance
Ze = External Earth Fault Loop Impedance
How to calculate fault current
To calculate fault current we need to know the two other required parameters.
- Earth Fault Loop Impedance (Zs or Ze)
- Voltage
The PFC calculation formula is:
- PFC = Voltage ÷ Zs (or Ze)
For example, if the voltage = 230 and Zs = 0.35 then,
230 (V) ÷ 0.35 (Zs) = 657 Amps x 1000 = 0.657 PFC kA
