Harmonic Resonance Frequency represents a signal or wave whose frequency is an integral multiple of the frequency of a reference signal or wave.
${ f = \frac{1}{2 \pi \sqrt{LC}} } $
Where −
${f}$ = Harmonic resonance frequency.
${L}$ = inductance of the load.
${C}$ = capacitanc of the load.
Calculate the harmonic resonance frequency of a power system with the capcitance 5F, Inductance 6H and frequency 200Hz.
Solution:
Here capacitance, C is 5F. Inductance, L is 6H. Frequency, f is 200Hz. Using harmonic resonance frequency formula, let's compute the resonance frequency as:
${ f = \frac{1}{2 \pi \sqrt{LC}} \\[7pt] \implies f = \frac{1}{2 \pi \sqrt{6 \times 5}} \\[7pt] \, = \frac{1}{2 \times 3.14 \times \sqrt{30}} \\[7pt] \, = \frac{1}{ 6.28 \times 5.4772 } \\[7pt] \, = \frac{1}{ 34.3968 } \\[7pt] \, = 0.0291 }$
Thus harmonic resonance frequency is $ { 0.0291 }$.
