Utility Bill and System Load

03/17/2010 10:32 AM

I have a utility bill for a site. It says the demand is 113kW. If the site is using 480V.. Does that mean the load is 135.91A?

113,000 / 480 * 1.732 ?

You need to allow for Power Factor, Captain, which will make it more. Divide by the cosine of the phase angle between the voltage waveform and the current waveform. Also, I'd drop some of those least-significant-digits if I were you.
