Relationship between line and phase current values in star connected load

$I_L=I_{ph}$

Where, IL = Line current ,       Iph = Phase current

Relationship between line and phase current values in delta connected load

$I_L=\sqrt 3I_{ph}$

Thus in delta - connected three phase system,line currents are 30o behind the respective phase currents.
