Variables Used
A-Phase Current LG - (Measured in Ampere) - A-phase Current LG is the current that flows into the a-phase in open conductor fault.
Zero Sequence Current LG - (Measured in Ampere) - Zero Sequence Current LG consists of a balanced three-phase current, phasors of which all have the same phase angles and rotate counterclockwise together.
Positive Sequence Current LG - (Measured in Ampere) - Positive Sequence Current LG consists of balanced three-phase voltage and current phasors which are exactly at 120 degrees apart rotating counterclockwise in ABC rotation.
Negative Sequence Current LG - (Measured in Ampere) - Negative Sequence Current LG consists of balanced three-phase current phasors which are exactly at 120 degrees apart rotating counterclockwise in ACB rotation.
STEP 1: Convert Input(s) to Base Unit
Zero Sequence Current LG: 2.2 Ampere --> 2.2 Ampere No Conversion Required
Positive Sequence Current LG: 2.001 Ampere --> 2.001 Ampere No Conversion Required
Negative Sequence Current LG: -0.36 Ampere --> -0.36 Ampere No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ia(lg) = I0(lg)+I1(lg)+I2(lg) --> 2.2+2.001+(-0.36)
Evaluating ... ...
