Answer 1

Answer #1

Power factor is nothing but proportional ratio between real power(kW) and apparent power.

Power factor (P.F)=Real power/Apparent power

There are two types of power factors.

One is lagging power factor and other is leading power factor.

Generally generators are rated in kVA at 0.8 power factor lagging which is nominal power factor helps to calculate

the kW output of an engine to supply the power for a particular alternate kVA output.

For example

Alternater output is 300kVA

Then engine power output=300kVA×0.8=240kW

Relation between Lagging power factor&Engine (kW)

If P.F is >0.8. our is engine is not capable of having sufficient kW power to the alternator to scent(100%) kVA rating....

If P.F is <0.8 engine having required kW to power the alternator in excess of its 100% of its kVA rating...

Like the above depending upon power factor power transferring capability varies.....
