Hydraulic-operated circuit breakers are critical grid assets, but periodic manual inspections often miss early signs of pump degradation. In this article, Yasunori Ito introduces a low-cost, continuous online monitoring system that tracks pump operation times and intervals. By analysing this behavioural data alongside ambient temperature variations, operators can detect anomalies early and transition to proactive, condition-based preventive maintenance.
