The amount of variation in loads across industries today varies the amount of compensation needed. To save as much energy as possible, power must be kept close to unity, so precise variation in capacitor rating is required. The capacitors must operate based on the variation of the load because these variations are periodic and even dynamic. APFC Panels are very helpful in achieving this goal, and their use in industries with constantly changing load patterns throughout the day makes them indispensable. Many power utilities have changed their power tariffs so that both lag and lead PF can experience higher losses and higher unit consumption.
