Monitoring a medium-voltage circuit-breaker: use case


The customer wanted to monitor a medium-voltage circuit-breaker, as it could be installed on a critical site. The customer wanted to market DiagFit to its own customers to increase product attractiveness. The customer wanted to sell hardware in addition to a digital solution like DiagFit.


The customer wanted a non-intrusive Edge solution and to check whether the circuit-breaker opening/closing device could perform a correct maneuver or required maintenance.


Diagfit analyzed data from a vibration sensor attached to the outside of the circuit breaker.

The opening/closing cycle produced vibrations which were analyzed by DiagFit to determine the state of health of the machine.


The model learned with no indication of failure in the blind data.

Very good detection (100% failure detection) with few false positives (1%) on laboratory test.
