Abstract

A digital twin for circuit breaker monitoring has been developed, focusing on the trip coil and adjacent mechanisms. The twin is based on a fast-to-evaluate system of ordinary differential equations (ODEs). It works as a soft sensor which integrates measurements of observable quantities (e.g. current, force) and parameter identification algorithms. The approach allows to infer the drift of non-measurable quantities such as damping. This gives new options for predictive maintenance and increased reliability of circuit breakers. Calculational results demonstrate the digital twin’s effectiveness in real-time monitoring and fault detection.
