Problem $2.$

synchronous generator $25PT$ A $100KW,440V,0\mathrm{.}85p.f.$lagging$\mathrm{.}50Hz,4$ pole A $-$connected full load condition, the fremature resistance of $0\mathrm{.}1$ and reactance of $2\mathrm{.}0.$ Under the Ignore any field che friction and windage losses are $6$ kW and core losses are $4$ kW $.$

a$)8PT$ Drat circuit losses.

magnitude the per phase equivalent circuit of the generator and calculate the supplying raled internal generated voltage Ea at the rated conditions $($Generator angled voltage, rated current at the rated power factor$)?$ What is the torque

b$)2$ PI at the rated conditions.

b$)[2$ PT$]$ How much field current would be required when this generator is operating at the rated conditions of part $($a$).$

c$)$ PT$]$ How much power is supplied to the generator by the prime mover. What is the overall efficiency of the generator.

d$)[4$ PT$]$ What torque must be supplied to the generator shaft by the prime mover.

e$)[3$ PT$]$ If the generator load is suddenly disconnected, what will be the generator output voltage. What field current should be supplied to adjust the output voltage to rated value.

f$)[4$ PT$]$ What is the maximum power that this generator is capable of supplying. What is the comparison of generator rated operating condition with the maximum possible output power $($Ignore the armature resistance for this part of the problem$).$
