by adding the capacitor bank in the circuit...

Answer / mubashar hussain arshad

we cam improve the power factor by capacitors... by
improving power factor the KVA rating of aquipments become
small so we can reduce the cast of equipments.... so by
improving the power factor one can get cost benefits and
size of equitments smaller

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 ?
