This way, several more current consumers connected existing supply system without having extend amplify that system capacitors suitably positioned. Individual Power Factor Correction power factor correction capacitor connected directly terminals consumer will switched together with advantages this method are: Relief conductor lines switches, capacitor switches discharge resistors needed, installation simple cheap. individual compensation best solution large consumers (e.g. motors), particularly they continuous operation. Individual Power Factor Correction 3-Phase Motors motor capacitor connected parallel. They both switched means same switchgear also monitored common protective device. discharge device required, because discharging takes place through motor windings. switchgear must rated capable withstanding inrush current capacitor connection lines must capable withstanding full load current motor. capacitor, this case, installed close proximity motor. Individual Power Factor Correction Power Transformers direct connection capacitor power transformer, which jointly switched out, feasible permissible both H.V. side L.V. side. cases where harmonics exist line, line should checked determine whether capacitors power transformer connected series create resonance. Care should taken overcompensate power transformer during load operation order avoid unacceptable rise voltage. Individual Power Factor Correction Welding Machines output capacitors welding transformers resistance welding machines only needs range nominal transformer capacity. welding rectifiers, capacitor output about nominal capacity transformer/rectifier sufficient. Group Power Factor Correction power factor correction capacitor connected secondary distribution system which feeds number individual motors, operating either continuously intervals. motors capacitors each switched separately monitored separate protective devices. capacitors switched individually groups.

Central Power Factor Correction large installations where many individual electrical appliances various size (motors etc.) operate different times different periods, power factor correction capacitors centrally connected main buss bar. capacitors switched either manually means power factor control relays, automatically. Advantage Automatic control optimal matching capacitor output specific requirements reactive power insures that specified maintained most cost effective way. Disadvantage conductor lines between buss electrical appliances relieved reactive current.
