Question

what is the main cause for below 0.5 lagging
Power factor in 3 phare systoup?​

Answer 1

Explanation:

The important inductive loads responsible for the low power factor are the three-phase induction motors (which operate at a 0.8 lagging power factor), transformer, lamps and welding equipment operate at low lagging power factors.

Answer 2

• Main cause of poor power factor are inductive loads . Power factor is ratio of Active Power to that of the Apparent power. So, inductive loads draw Reactive power which increases Apparent power but active power consumption is less . Hence, Power factor becomes poor. Some of the equipment which uses reactive power are 3 phase induction motors ,  transformers & welding machines.
