Calculate reactive power of the capacitor bank and improve power …
Example calculation. In a plant with active power equal to 300 kW at 400 V and cosφ= 0.75, we want to increase the power factor up to 0.90 the table 1 above, at the intersection between the row "initial cosφ" 0.75 with the column "final cosφ" 0.9, a value of 0.398 for the coefficient K is obtained. Therefore a capacitor bank is necessary with …
Why reduce reactive power? More power
The capacitor bank is the most well-known solution for reducing reactive power and has been used for decades. The capacitor bank is - as the name implies - a cabinet full of capacitors with which the reactive power for the coil is supplied. As a result, the reactive power for the capacitor bank has disappeared and a cos-phi of 1 is measured.

why does capacitor supply reactive power?
Vidhyut''s question is as I undertand that Capacitor when used in power factor improving applications,it supplies reactive power and so compensates for gneration of reactive power by Inductors. In Q=VISin(phi)–>when phi=-90 ie from if you can remember vector diagram of I & Ic –>it is (-Q )–>so again negative power.so capacitor is …
