Answer Posted / ramendra shukla
In Y- connected load (3 phase)
1) If Ir= Iy=Ib then In=0 (Symetrical /balance)
2) If Ir#Iy#Ib ; then In=x (Unsymetrical/unbalanced)
where; Ir,Iy,Ib &In are phase &Neutral current
respectivelyand also #is is not equal
3)but in case of Single phase looping the avilability of
current will be.
