Overview
Transformers are critical assets in power distribution and industrial operations. Unexpected transformer failures can lead to extensive outages, safety hazards, costly emergency repairs, and reputational damage. Traditional maintenance based on time schedules often fails to catch early signs of insulation degradation, overheating, or moisture ingress, leading to unplanned downtime.
AI-powered Predictive Maintenance enables early detection of transformer health issues, ensuring planned interventions, reducing downtime, and extending asset life.
Solution
An AI-based Predictive Maintenance system was implemented for transformers by:

IoT Sensor Deployment
Deploying IoT sensors to monitor critical parameters, including oil temperature, winding temperature, dissolved gas analysis (DGA), load patterns, partial discharge, and moisture levels.

AI-Based Anomaly Detection
Developing AI models that process live sensor data to detect anomalies and predict potential failures.

Actionable Maintenance Alerts
Providing actionable alerts for maintenance teams to plan interventions before failures occur.

System Integration
Integrating predictive insights with asset management systems to align maintenance with operational workflows.
This system allows utility operators to transition from reactive to proactive transformer maintenance, improving reliability while reducing maintenance costs.
