Power Factor of diesel generator sets
Power Factor (PF) is the ratio of the actual power supplied to the circuit according to the appliance. As electricity flows, there is unavoidable energy loss in heat and resistance. The value of Power Factor ranges from 0 to 1.
Formula: PF = kW/kVA
To maximise the performance, the standard-setting of our engines and generator sets is at 0.8PF. For example, a 400 kVA diesel genset with a 0.8PF has an actual output 320kW.
In rare situations, some clients may require Power Factor apart from 0.8 for their generator units. For example, a 400 kVA diesel genset with a 1 PF will have an actual output 400kW. But note that a low PF generates excessive heat and losses, leading to poor system efficiency.
