The desired power factor value is 1. The PF is closest to 1 if the load is pure resistive. In an industry, the load is mix of resistive and inductive, more so largely inductive, the power factor tends to be less then 1 , lagging, which is not desirable. Hence power factor regulator (controller) together with suitable capacitor banks (to compenesate for lagging PF , in order to bring it towards unity (1)) are used in industry. Capacaitor banks are generally connected to load side, closer to loads. Practically to PCC or MCC locations. Capacitor banks are never connected to Generator sets.
