What is difference between line current and phase current?

Line current is the current through any one line between a three-phase source and load. Phase current is the current through any one component comprising a three-phase source or load.

What are the Sequence Components?

The positive sequence consists of balanced three-phase voltage and current phasors which are exactly at ₁₂₀ degrees apart rotating counterclockwise in ABC rotation. The negative sequence consists of balanced three-phase voltage and current phasors which are exactly at ₁₂₀ degrees apart rotating counterclockwise in ACB rotation. Zero sequence consists of a balanced three-phase voltage and current, phasors of which all have the same phase angles and rotate counterclockwise together.
