  1. What a lot of people are missing is that power factor is a measurement of how out-of-phase the voltage and current are in a AC circuit. If the two peaks don't coincide then the actual power measurement becomes skewed. It's difficult to imagine this happening but it does. Years ago large numbers of fluorescent lights in large factories was a major cause but today it's more likely to be caused by a process machine like a RF induction heater. I've always seen it requiring the installation of a capacitor bank in the factory switchyard to bring it back to a reasonable value.

  2. Be a skeptic with electric! Lockout, tryout, tagout. Don't trust anyone with your life.
