The ratio of the reactance of the tuned circuit to its
resistance is called the "quality factor", or Q factor, or
simply Q. Thus, Q is the ratio of the energy stored to the
energy dissipated in the circuit per cycle.

Q is a measure of the 'sharpness' of the response of the
tuned circuit to the resonant frequency. Thus, a circuit
with a high Q will exhibit a higher amplitude at the
resonant frequency, but will decay more quickly as the
frequency moves away from the resonant frequency.

Exactly Thanks for posting such nice concept

Answer / bryan

what is Q factor and why is it important in high and low
frequency circuits?

Electricty is generated at around 16kV, then step up to 220kV for transmission then steped down to power transformers then DTs and then through the LT n/w it reaches the consumer end. At the consumer end 230V supply is required. So, why is electricity not generated directly at 230V and transmitted?

we have one pumping station and 4.6 MW 7 no.s synchronous motors.so there is no required HT capacitor to improve power factor.But we have two no.s of 25 Mva power transformer connect to distribute the power for motors connect with 220 kv line.So i have required the HT capacitor to improve power factor at HT side i mean power transformer bus side.So please suggest how much HT capacitor banks required for same.
