What is auto-transformer? what is its functions?
and what does capacitor have to do with auto-trans?
what is capacitor bank (which would be suited inside the starter)?
and why is its capacitor units are in KVAR? what's the difference between KVA and KVAR?
Auto-transformer is a single-winding transformer with taps. With primary voltage applied to the primary terminals, the required secondary voltage from zero volts to the rated primary volts can be availed from the secondary by varying the taps. The advantage
