I understand that all fluorescent light fittings with ballasts have capacitors fitted to correct the power factor. But do many factories/machine shops etc have capacitor banks? Are motors (large or small) supplied with capacitors by the manufacturer for power factor correction? (I think not?)
I work at a factory as electronic specialist and from what iv seen no. The only places I have seen capacitor banks have been on circuit boards. Our electric motors are just ran off of motor contacts of VFDs if we need a variable speed. All our DC photoeyes and other things we have a DC power supply which also has a capacitor bank inside. Thats about it tho
