Positive Sequence Impedance in L L Fault Formulas
Positive Sequence Impedance consists of balanced three-phase voltage and current phasors which are exactly at 120 degrees apart rotating counterclockwise in ABC rotation. And is denoted by Z
1
. Positive Sequence Impedance is usually measured using the Ohm for Electric Resistance. Note that the value of Positive Sequence Impedance is always positive.
