A $380V,50Hz\frac{,}{{?}_{\frac{?}{?}}}-$connected, eight poles synchronous generator has the OCC given ~$|||$ In tabular form below. The generator has a per$-$phase synchronous reactance of $0\mathrm{.}205,$ and negligible armature resistance. At full$-$load, the machine supplies $I_A=690$A 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 full$-$load. Ignore stray losses, and any field circuit losses.
