I was asked how to calculate the power to a 3 phase delta connected heater if the load is not balanced. We all know the formula W = LV x LA x 1.732 x PF for 3 phase power but I can't remember how to do the same for an un-balanced load. My intuition tells me that using the average current for LA would be close but that seems too simple.
Anyone remember the formula?
Thanks,
