There exist good, bad, and poor power factors with specific ranges where 1.0 to 0.95 is said to be good, 0.95 to 0.85 poor, and 0.85 and below is said to be bad. When the system achieves a power factor of 1.0, the system is approved to be perfect. Poor power factor originates from a system''s resistive, inductive, and capacitive loads.
