Hi guys. This is for my revision. I can't find enough information anywhere so I count on You 1. What are two ways of correcting power factor? I know about caps but what is the second one??? 2. What effect motors have on the supply and why they need their power factor corrected? I know there are some kind of supply comany requirements that businesses must obey but cant find anything about it either. Also how it affect cable size/cost and switchgear cost? 2. I need two examples of eqiupment/situations that produce unwanted harmonics. Any ideas? Thanks.
