Zero Sequence Current in L L G Fault Formulas

Zero Sequence Current consists of a balanced three-phase current, phasors of which all have the same phase angles and rotate counterclockwise together. And is denoted by I₀. Zero Sequence Current is usually measured using the Ampere for Electric Current. Note that the value of Zero Sequence Current is always negative.
