To selecting rating of tr considering 3 points

1) connected load
2) Power factor
3) Future expansion

KW=KVA*PF

Answer / rajeshsan

The rating of Transformer is sized based on many factors:-

1. Total load demand
2. Design margin
3. Continuous load with certain margin with intermediate load
4. In case of Thermal Power plant, Factors like Worst coal, Test block condition for Worst coal..

Our Alternator nameplate specifies a power factor of 0.8. When the Alternator is on light load, the bus bar voltage rises to 11240 volts, whereas the standard value is 10500 volts. Is it ok to increase the power factor to 0.85 or 0.9. I am afraid because the power factor on the name plate is only 0.8 ?
