Understanding Power Factor Correction (PFC) Capacitors
Where Are PFC Capacitors Installed and What Do They Do? PFC capacitors are typically installed either locally (for equipment like DOL motors) or at the main distribution board (bulk correction). By supplying reactive power locally, PFC capacitors reduce the overall current drawn from the grid, which decreases electricity wastage and improves
capacitor
A capacitor in an AC circuit forms a current limiter because when current flows one way the capacitor lets it pass until the capacitor is charged in one polarity and then when the current is reversed the capacitor discharged and lets the current flow the other way. Unless you need some current to pass constantly to power this special kind
