I have been working on a project to calculate the enegy cost savings that would result by turning off large 3-phase pumps during peak energy cost
hours of the day.
How is the power drawn by a 3-phase motor calculated ? Is the equation, 3^0.5 * V * A, correct and independent of the load on the motor ? Is it more accurate than using motor horse-power and efficiency to calculate power draw ? What formula do the electric utilities use for their load shedding calculations ?
Thanks in advance.
