They show before and after electric bills and everything!
Great day to be alive!

This is because of uneven distribution of current over the cross section of the conductor leads to a significant reduction in the cross section of the actual current-carrying part of it and, consequently, to an increase in its active resistance.haklesup wrote: ↑Fri Mar 08, 2019 2:09 pmJust a power factor corrector and not a very big one either. That youtube video was very good at explaining this product and its shortcomings
Seems to be an incidence of taking real engineering theory and misapplying it to a situation to make money. Most inductive appliances already have PF correction built in, just look in any ceiling fan, the same black box caps are used.
PF Correction is mainly applicable in heavy industry where the reactive power though not measured, if significant can still cause resistive losses in the conductors which is not returned to the utility.
