Condition Reports: Automated generation of detailed health reports for specific CTs or entire fleets.
Historical Analysis: Tools for deep diving into historical data for root cause analysis and performance benchmarking.

Primary Use Case: Remote Substation Monitoring & Optimization

Scenario: Gasar da ake amfani da CTs a wurare da kisan kisan karkashin tattalin aiki (mountains, deserts, rural grids). Aiki da kisan karkashin tattalin aiki suna daidai, ma yawa, da kuma logistically complex. Reactive maintenance after failure leads to extended outages.
Solution Benefits:

Eliminate Unnecessary Visits: Move from calendar-based to condition-based maintenance. Only dispatch technicians when truly necessary based on AI predictions or specific critical alerts.
Prevent Catastrophic Failures: Early detection of developing PD activity, moisture ingress, or thermal anomalies allows intervention before the CT fails catastrophically, avoiding costly collateral damage and prolonged outages.
Optimize Maintenance Resources: Focus scarce technician time and budget on high-risk assets identified by predictive analytics, improving overall grid reliability.
Remote Diagnostics: Provides deep insight into CT condition without requiring on-site physical presence for initial diagnosis. Empowers remote experts to guide local crews.
Extended Asset Lifespan: Proactive management of conditions degrading the CT (heat, moisture) helps maximize operational life.

Key Implementation Considerations

Edge Processing: Basic filtering, buffering, and preliminary anomaly detection occur locally on the CT module to minimize unnecessary data transmission and improve response time for critical events.
Power: CT-powered options for primary connectivity, with battery/solar backup for critical sensing and alerting during primary power loss.
Cybersecurity: Robust design adhering to industry standards (IEC 62443, NERC CIP) is paramount. Secure boot, encrypted communication, secure device management.
Scalability: Cloud platform designed to handle data ingestion and processing from thousands of CTs across a large utility network.
Integration: Open APIs allow integration with existing Asset Management Systems (EAM/CMMS), SCADA systems, and enterprise data lakes for holistic visibility.
Calibration & Validation: Established procedures to validate sensor accuracy and AI model performance against known conditions.
