1.	Calculate the value of voltage regulation at 0.8lagging for a transfomer' withresistance drop 2% and reactance drop 4% of the voltage
Answer» % Voltage REGULATION = %R * cos Φ ± %X * SIN(Φ)Plus (+) sign is for lagging POWER factor and minus (-) sign is for LEADING power factorGivencos Φ = 0.8sosin Φ = 0.6% Regulation = %R * cos Φ ± %X * sin(Φ)% Regulation = (20.8)+(50.6)% Regulation = 1.6 +3% Regulation = 4.6%
