Re: UPS VA ratings (was: Re: [PLUG] equipment give-away on Wed evening)


Power Factor is cool. When an electric motor starts, for example, it can make use of a capacitor to counteract the inductive load of the motor, so it will start easier. If you have a capacitive load, you can use an inductor to compensate. It's fun to actually see it happen, either physically or on a scope.

load actually dissipates that much power. The electric company spends a lot of money putting capacitor banks at substations to try and raise the power factor to 1.0 to cut their generating costs.
