A synchronous motor has the following parameters per phase. E=2kv, Eo=5kv, X2=3ohms, and I=700amps. Draw the phasor diagram and determine
(a) power angle delta,
(b) active power(3phase),
(c) reactive power(3phase),
(d) power factor of the motor. If the load is removed suddenly, calculate
(e) the new power angle and
(f) new reactive power(3phase).
