Consider the three phase generator below: a) If the stator rotates at 2400 rpm, what is the frequency of the voltage generated? b) If the generator is connected to a balanced, wye-connected, resistive load as shown below and a phase current of 100 A is required, what is the phase voltage that the generator must supply? What is the minimum power rating (in MVA) the three phase generator can have?
A wye-connected, 3-phase generator is rated 90 MW, 13.8kV and 0.9 pf. The dc resistance of the armature is obtained by connected two of its terminals to a 6 Vdc source. The current drawn by the armature is 87.6 A. What is the percent effective resistance of the armature of the generator?
