Case Study: How Samarco Turned Existing Reclosers into an Energy Monitoring Tool

For modern industrial operations, understanding energy performance is becoming just as important as keeping critical assets protected.

At Samarco’s mining operations in Brazil, engineers were seeking greater visibility into the electrical behaviour of a conveyor system with unique operating characteristics. While the network was already protected by NOJA Power reclosers, the team identified an opportunity to gain deeper operational insight without installing additional monitoring equipment.By leveraging the Load Profile functionality available within the existing reclosers and integrating the data into Samarco’s monitoring environment, NOJA Power and Samarco transformed protection devices into a practical energy monitoring solution. This enabled the team to accurately quantify energy consumption and regenerative energy contribution, better understand the financial impact of system operation, and identify opportunities for further optimisation.

The project demonstrates how intelligent reclosers can deliver value beyond protection, providing actionable insights into network performance, energy behaviour and operational efficiency while maximising the value of existing infrastructure.
