Power Factor Correction Guides Page 2: 32 technical guides for choosing Power Factor Correction products: selection criteria, standards, common mistakes and frequently asked questions.
Three-Phase Power Factor Correction Capacitors Selection Guide — A three-phase power capacitor is not a harmonic filter on its own; in facilities with harmonics, it is used in series with a suitable filter reactor. Power Capacitors Selection Guide — Engineering guide to selecting single-phase and three-phase cylindrical and box-type power capacitors (kVAr, 400 V / 450 V / 525 V) for PFC banks. What Is an Energy Analyzer? Power Network Analyzer Selection Guide — An energy analyzer measures and displays voltage, current, power and energy; this selection guide covers DIN rail and panel types, harmonics and Modbus features. Power Factor Correction Selection Guide — Power factor correction raises the power factor by supplying the reactive power drawn by inductive loads locally with capacitors. Panel components and calculation method. Current Transformers Selection Guide — A current transformer is an instrument transformer that reduces the high primary current by a set ratio and passes it to meters and relays. Busbar, cable and split-core types. Shunt Reactors Selection Guide — LED drivers, UPS units and XLPE cable runs can push a facility capacitive; for shunt reactor selection, the cause and the reactive energy limit matter. Harmonic Filters Selection Guide — Harmonic filters come in three-phase, single-phase and active types; a value like 7% is the reactance ratio and sets the step's resonance frequency. Motor Capacitors Selection Guide — A run capacitor stays in the circuit as long as the motor runs, while a start capacitor drops out once the motor has started; selection rests on this difference.
