ISA Energía Perú is digitizing SF₆ gas leak monitoring in 220kV and 500kV substations to enhance environmental care and operational reliability. SF₆, a greenhouse gas used in circuit breakers, was previously monitored manually. Now, sensors measure pressure, density, and temperature in GIS compartments, with data integrated into PI System and Azure Data Lake for predictive analytics. Results return to PI via PI Connector for UFL and are visualized in PI Vision. SCADA alerts via email improve response. This initiative reduces emissions, automates data collection, enables early leak detection, and improves maintenance planning.
