power factor is cosine angle of voltage & current in vector diagram,& is ratio of real power to apparent power.. we maintain in our organisation as installation of capacitor bank. its valve in between 0.95 to .99. but valve of p.f. below the 0.9 & above 1.0 organisation get penalty charges as per Msedcl act.. maintaining p.f. means keeping resistance of circuit unity.or balance the resistance of inductive load to resistative load in circuit by capacitance load.
