Intellectual analysis of the technical condition of high‑voltage circuit breaker and quality control of wear recovery

A model for assessing the residual life of high voltage circuit breakers is proposed. The initial data used include data on the consumption of commutation life by short-circuit clearings, as well as data on changes in circuit breaker component wear due to mechanical, electrical, and thermal effects. Intelligent analysis of circuit breaker diagnostic results includes information on the circuit breaker’s technical condition; analysis of the circuit breaker component wear rate; the date and scope of circuit breaker monitoring; circuit breaker wear dynamics, etc. The analysis allowed developing information and methodological materials to support personnel for the purpose of improving the efficiency of facility planning and wear restoration timelines, reducing the risk of wrong decision.
