XL=2Ï€fl
XC=1/2Ï€fc
if XL=XC
then2Ï€fl=1/2Ï€fc
this is the condition of resonance
due to resonance the current flowing in the circuit is very high due to high current risk damege of equipment.
for the protection of the resonance we use reactor for the protection . it works as a low pass filter . Only pass up to the fifth harmonic of the resonance.
