Positive Sequence Current in L L G Fault Formulas
Positive Sequence Current 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 I
1
. Positive Sequence Current is usually measured using the Ampere for Electric Current. Note that the value of Positive Sequence Current is always negative.
