How to Calculate Fault Current(LLF)?
Fault Current(LLF) calculator uses Fault Current = (sqrt(3)*A Phase EMF)/(Positive Sequence Impedance+Negative Sequence Impedance) to calculate the Fault Current, The Fault Current(LLF) formula is defined as the high level of electrical current that flows in a power system when a fault occurs. Fault Current is denoted by If symbol.
How to calculate Fault Current(LLF) using this online calculator? To use this online calculator for Fault Current(LLF), enter A Phase EMF (Ea), Positive Sequence Impedance (Z1) & Negative Sequence Impedance (Z2) and hit the calculate button. Here is how the Fault Current(LLF) calculation can be explained with given input values -> 0.968551 = (sqrt(3)*29.38)/(7.94+(-44.6)).
