Answer #1

Power Factor determines the efficiency of a Electrical system. power Factor is given by the formula,

  

Power Factor must be close to unity for efficiency to be high.

Low power factor occurs in unavoidable inductive loads.

This can be corrected by injecting leading current.

Some of the methodologies for power factor correction are

A 3 phase, 3.3 kV industrial plant has an overall power factor of 0.88 lagging. A 200 kVA synchronous motor is added to the system and is run at zero power factor and slightly reduced rating to provide power factor correction only. The total load is then 350 kVA at unity power factor. It was then decided to run the synchronous machine at its rated kVA and use it as a source of mechanical power, what gross mechanical power would...
