What is the importance of quality factor in resonance?
Answer Posted / raghavendran.r
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.

Instrument connected to a single phase supply
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The rotor reactance at stand still is A 2 ohm B 1.25 ohm C 3.15 ohm D 2.25 ohm
