Answer / nagaraju thangella

The powerfactor plays an important role in AC Since pwr consumed depends on PF
A PF Less than unity results in
Larger kva rating of equipment.
Larger copper losses
Poor voltage regulation
Reduced handling capacity
KW=KVA Cos phi
Hence we correct power factor

Answer / majid dadjoo

with reactive power corection you can decrease reactive
power on line . it means that by reducing reactive
power ,same active power can transmit by a line with lower
current than previous.

Answer / gms

adding to the above explanation we can say it is required to maintain a flat voltage profile in the line and control the flow of reactive power
