To find the full load real power delivered by a three-phase generator, the formula used for calculating real power (P) in kilowatts is:

[ P (kW) = \sqrt{3} \times V \times I \times \text{Power Factor} ]

Where:

  • ( V ) is the line-to-line voltage in volts

  • ( I ) is the current in amperes

  • The power factor accounts for the phase difference between the voltage and current.

In this case:

  • The terminal voltage ( V = 600 , \text{V} )

  • The current ( I = 200 , \text{A} )

  • The power factor = 0.80 (which is 80%)

Plugging in these values:

  1. Calculate the full load real power using the formula:

[ P = \sqrt{3} \times 600 \times 200 \times 0.80 ]

Calculating step-by-step:

  • First, calculate ( \sqrt{3} ) (approximately 1.732).

  • Then, multiply:

  • ( 600 \times 200 = 120,000 )

  • Then, multiply by the
