Answer / raghavendra

these are balanced symmetrical cmponents to represent 3phase
unbalanced system by using perator K.(-0.5+i.866) in order
to reduce the complexity.

Answer / ansar tarala

they are volatage/current components co-existed in three phase unbalanced system. unbalanced 3phase s/m can be easily analysed by considering these components.

Answer / upendra

they are the component currents for EACH OF three
phases

Answer / x man

ITS USED TO REPRESENT DC POWER SYSTEM.

how can we minimize the off load losses of a distribution transformer which is required to be energized 24x7 ?? capacity of the T/F is 1250 KVA and off load losses are around 2.0 KW.. can we use capacitor bank at the secondary of such a T/F to overcome off load losses? please elaborate briefly...thanks
