A$.\backslash (380\backslash$mathrm$\{$~V$\},50\backslash$mathrm$\{$~Hz$\}\backslash ).\backslash (\backslash$triangle $\backslash )-$connected, eight poles synchronous generator has the $\backslash (0$ C C $\backslash )$ given in tabular form below. The generator has a per$-$phase synchronous reactance of $\backslash (0\mathrm{.}205\backslash$Omega $\backslash ),$ and negligible armature resistance. At full$-$load, the machine supplies $\backslash (\backslash$mathrm$\{$l$\}\_\{\backslash$mathrm$\{$A$\}\}=690\backslash$mathrm$\{$~A$\}\backslash )$ armature current at $0\mathrm{.}85$ PF lagging. The generator has friction and windage losses of $40$ KW and core losses of $30$ KW at fullload Ignore stray losses, and any field circuit losses.

The internal generated voltage of this generator will be $\backslash (=\backslash )\backslash (\backslash$checkmark $\backslash )$ with a torque angle degree, and the field current that must be supplied to the generator $=$ A

$3-$The output power supplied by this generator at fuli$-$foad $\backslash (=\backslash ).$ KW

$4-$ The shaft torque must be applied by the prime mover at full$-$load$=$ Nm

$5-$ The maximum power that can be supplied by this generator$=$ MW
