Q1) a balanced 3 phase load has 3 coils, each with resistance of 27ohms & Inductance of 0.02H connected across a 3 phase 400 V, 50 Hz supply.
a) Determine the total Power dissipated iwhen the coils connected in star
B) det. the total pwer dissipated when the coils are connected in Delta.
Q2) 3 impedances each having a resistance of 10ohms and an inductive reactance of 25ohms are connected in star across a 400V 3 phase supple, calculate:
a) the line current
B) the power factor
c) the total power in kW
Q3) a 230V 3 phase voltage is applied to a balanced delta connected in 3 phase load of phase impedance (33-J25)ohms, calculate
a) the current in each phase
B) the active power consumed
c) the total reactive power supplied
