Electrical Load Calculation

10/15/2011 5:43 AM

We have a Gas Generator of 325 KVA.

When all three Ampere Meters are showing 200 A each.

1. How many units (KWH) are consumed in 10 hours.

2. What is the percentage of Load.

3. The name plate of AC Generator indicates 380/220 volts, 494 Amps. What does this means.

380 V × 494 A × √3/1000 ≈ 325 KVA; so the numbers are consistent.

If the power factor is 0.80, then 325 × 0.8 = 260 KW; this might also appear on the nameplate.

At 200 A, the genset is about 40% loaded, producing about 130 KVA and 104 KW. In 10 hours, it will produce about 1040 KWH.
