How to Calculate Fault Impedance given Sequence Voltages(LGF)?
Fault Impedance given Sequence Voltages(LGF) calculator uses Fault Impedance LG = (Zero Sequence Voltage LG+Positive Sequence Voltage LG+Negative Sequence Voltage LG)/(3*Positive Sequence Current LG) to calculate the Fault Impedance LG, The Fault Impedance given Sequence Voltages(LGF) formula is defined as the impedance which is connected to the earth. Fault Impedance LG is denoted by Zf(lg) symbol.
How to calculate Fault Impedance given Sequence Voltages(LGF) using this online calculator? To use this online calculator for Fault Impedance given Sequence Voltages(LGF), enter Zero Sequence Voltage LG (V0(lg)), Positive Sequence Voltage LG (V1(lg)), Negative Sequence Voltage LG (V2(lg)) & Positive Sequence Current LG (I1(lg)) and hit the calculate button. Here is how the Fault Impedance given Sequence Voltages(LGF) calculation can be explained with given input values -> 8.521739 = (17.6+17.5+16.056)/(3*2.001).
