Use this calculator to determine
if
installing capacitors is worth the investment. This calculator asks 6 questions
and then computes a rate-of-return and a payback period.
If the IRR is positive, this calculator will also compute how much positive
cash flow this investment will generate over a 10 year estimated
life.

To perform the calculations, we need three
items from your electic bill, plus two items that will be obtained by looking at the nameplate of the incoming transformer feeding your
facility. Those two additional items are used to determine whether the capactitor
should be slightly increased or decreased to insure that we do not cause a resonance condition.
Resonance is caused when a capacitor interacts with the transformer reactance, causing dangerous
overvoltage conditions.
