A 11KV, 1000KVA, 3phasor star connector alternator has a resistance of 2ohm per phasor , the open circuit curve & the character istion with rated full load outent at zero power factor are given in the following Table : find the voltage regulation of the alternator for full load current at power factor of0.8lagging.
| $I_f$ ampere | $---$ | 40 | 50 | 110 | 140 | 180 |
|---|---|---|---|---|---|---|
| Line voltage | $---$ | 5800 | 7000 | 13750 | 13750 | 15000 |
| Line voltage,zero power factor | $---$ | 0 | 1500 | 10550 | 10550 | 12500 |
