How to Calculate Positive Sequence Current using Fault Impedance(LGF)?
Positive Sequence Current using Fault Impedance(LGF) calculator uses Positive Sequence Current LG = (Positive Sequence Voltage LG+Negative Sequence Voltage LG+Zero Sequence Voltage LG)/(3*Fault Impedance LG) to calculate the Positive Sequence Current LG, The Positive Sequence current using fault impedance(LGF) formula is consists of balanced three-phase voltage and current phasors which are exactly at 120 degrees apart rotating counterclockwise in ABC rotation. Positive Sequence Current LG is denoted by I1(lg) symbol.
How to calculate Positive Sequence Current using Fault Impedance(LGF) using this online calculator? To use this online calculator for Positive Sequence Current using Fault Impedance(LGF), enter Positive Sequence Voltage LG (V1(lg)), Negative Sequence Voltage LG (V2(lg)), Zero Sequence Voltage LG (V0(lg)) & Fault Impedance LG (Zf(lg)) and hit the calculate button. Here is how the Positive Sequence Current using Fault Impedance(LGF) calculation can be explained with given input values -> 11.368 = (17.5+16.056+17.6)/(3*1.5).
