For a three-phase generator, the full load current is calculated as I = 1000 × S / (√3 × V). Where, S is the generator rating in kilo-volt-ampere (kVA), and V is the generator rated voltage in volt (V). For a single-phase generator, the full load current is calculated as: I = 1000 × S / V.

How do I calculate generator load?

For a three-phase generator, the full load current is calculated as I = 1000 × S / (√3 × V). Where, S is the generator rating in kilo-volt-ampere (kVA), and V is the generator rated voltage in volt (V). For a single-phase generator, the full load current is calculated as: I = 1000 × S / V.

How much load should you put on a generator?





Optimal operating conditions for gas generator sets can range from 50 percent to 100 percent of the rated load.
