Answer to Question #164994 in Electrical Engineering for Chuchu
Question #164994
A single-phase load takes 55 kw at 70% pf lagging from a 240V, 50 HZ supply. If the supply is made 60 Hz, with the voltage remaining the same what will be the KW load at 60 Hz?
Expert's answer
W=55 kw, pf= 0.7 lagg , V=240 volt,f=50Hz
V2= 240, f=60 for constant power factor and constant voltage load will be constant
W2= 55 kw
