A 50 hp, 460 V, three phase induction motor draws 61 amps when operating at rated voltage and at a power factor of 0.85 lagging when supplying a rated load.
knowns:
1hp=746watts
effeciency (n) = Pout/Pin = Pout/(Pout+losses)
Find:
A) Effeciency?
B) the reactive power drawn from the line?
C) the complex (volt-amperes) drawn from the line?
