why in three phase 440 circuit in all phase current is
almost equal L1-35 A,L2-34 A ,L3-31 A but in nutral when i
check with clamp meter it shows 25 A?
Answer Posted / kiran
Principle is vector summation.
Ir + Iy + Ib = 0
and not arithmatic summation.
Since neutral current is substantial 25A, the three RYB
vectors are not 120 degree apart. Means powewr factor in
each phase differs drastically. Thats why though there is
no much difference in RYB current, neutral has substantial
current.
