Power Consumption

06/30/2008 3:34 AM

Good afternoon, I know my question is a little elementary however I would like to ask your opinion.

How do you represent 3 Phase Power and single phase power on the basis of consumption? what could be the best example so that non-technical people could understand it fully?

Thank you!

Huh?

If you have a three-phase load, and it's 1 HP, then it's still 746 Watts per HP. If you have a single-phase load, and it's 1 HP, then it's still 746 Watts per HP.

If you want to know how many amperes per phase in a three-phase circuit as compared to the phase current in a single-phase circuit for similar loads, then divide Watts by (volts X PF X 1.73).

If you want to know something other than the very little I have told you, then you'll have to be more explicit.

Thank you for the enlightenment.

Actually, it was the same explanation I used, unfortunately the higher management could not digest that the 3 phase could be compared with a single phase power with regards to consumption.

So in my frustration, what I showed to them is the cost of installation and the return of investment just to compare the two loads. Luckily it worked.

Thanks again for the re-assurance. have a great day!
