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 ?

It is not advisable to run the gen at a pf lower than 0.8.
You can surely run at a better pf.

ASTM D 3455 - Standard Test Methods for Compatibility of Construction Material with Electrical Insulating Oil of Petroleum Origin has been used for Testing Transformer Oils with a product placed in it. Aged Control Oil has a Power Factor of 0.032% at 100°C. Aged Oil with a Test component has a Power Factor of 0.093% at 100°. Is this increase acceptable? If not why? How much increase is acceptable?
