WebApr 10, 2024 · Causes of low power factor: Most of the AC motors are of induction type (1φ and 3φ induction motors) which have a low lagging power factor; These motors work at a power factor which is extremely small on light load (0.2 to 0.3) and rises to 0.8 or 0.9 at full load; Arc lamps, electric discharge lamps and industrial heating furnaces operate at ... WebDisadvantages of poor power factor Since kVA is inversely proportional to the p.f., hence smaller the p.f of the load, higher will be the kVA rating of the transformers, generators and switchgear used. At a fixed kW, the cables will carry more current if the p.f. is low. Hence, this increases the size of cables to be used.
