Single-Phase Power Factor Correction

As far as I know, except for some kludgy ideas (and even scams), there is not much domestic application of power factor correction. But there might be recent developments that I'm unaware of.

Perhaps the best way to do it would be for manufacturers of motorized equipment to include capacitors, but aftermarket measures are likely to be awkward and uneconomical--not a typical DIY project, either.

As low power factor is not usually penalised on domestic tariffs, the application of power factor correction to it is sparse.

It would be good to identify specific domestic loads with which their power factor (p.f) can be improved. Say I have a T8/36W florescent light fitting with a ballast p.f of 0.80, I can replace the ballast with an energy efficient electronic ballast of 0.95 p.f. This will improve the lights loading efficiency, or I could replace the whole fitting with a T5/28W energy efficiency electronic fitting and tube at a p.f of 0.95, with the equivalent luminosity as compared to the traditional T8/36W fitting. Having installed a number of these energy efficient lights in a room with an air condition will also improve the air condition's loading efficiency. Additional, with an improved energy efficiency, the continues or variable loading stress on the supply sub switch board will be reduced. It may help if you are specific with your load application, which may possible have energy efficiency options to look at. Regards, Ron
