MathJax cleanup.

Imagine if one phase had 1000kVA but power factor of 0.01 giving real power of 10kW Another phase had 10kVA with a power factor of 1.00 also giving 10kW. With the third phase having no load the total power would be 20kW. If you calculate the average first you would have a power factor of .505 (ignoring the third phase) with 1010kVA giving an incorrect power of 510.05kW instead of 20kW. The power factor is related to one phase only if the phases are unbalanced in any way. With a balanced load all three power factors should be the same and it will not matter. | |

No thanks necessary ;)
