Negative Sequence Impedance LG in L G Fault Formulas
Negative Sequence Impedance LG consists of balanced three-phase impedance phasors which are exactly at 120 degrees apart rotating counterclockwise in ACB rotation. And is denoted by Z
2(lg)
. Negative Sequence Impedance LG is usually measured using the Ohm for Electric Resistance. Note that the value of Negative Sequence Impedance LG is always negative.
