what is mean by of PF corrected and PF not corrected

"PF corrected" means that a capacitor has been added to the lighting circuit of the discharge lamps in order to increase the power factor ([math]\displaystyle{ \mbox{cos }\phi }[/math]). "Not corrected" means without this additional capacitor. As you can see in the table, with this compensation capacitor, the current demand is reduced. You can find more about power factor correction in the chapter Power factor correction and harmonic filtering --LMischler 14:46, 28 December 2010 (UTC)
