Open Circuit Test on Three Phase Alternator
The power factor of an alternator under short circuit conditions is almost near
In a 3-phase cylindrical-rotor alternator,
A cylindrical-rotor synchronous generator will deliver maximum power output when
A 3-phase synchronous generator is operating at a constant load while the excitation is adjusted to give unity pf current. If the excitation is now increased, the pf will
A synchronous motor with negligible armature resistance runs at a load angle of 20° at rated frequency. If supply frequency is increased by 10%, keeping other parameters constant, the new load angle will be
