The essence and deficiency of the conventional modelling method based on exponentially damped oscillatory waves are analyzed
and an improved modelling method based on the distortion phenomenon in propagation of the vibration signals of circuit breakers is proposed. A self-study optimization modelling strategy is set up in the frequency domain
and its validity and feasibility are preliminarily verified by an example. The modelling method shows a new theoretical basis and techniques for monitoring and diagnosing of the mechanical condition of high voltage circuit breakers.
