Power systems are changing fast: decentralized generation and higher loading push grids to their limits while skilled staff is limited. In this environment, online monitoring becomes a key tool to maintain reliability and optimize maintenance based on actual condition.

 

This webinar cuts through complexity and shows a practical, cost‑effective pathway to monitor what matters most on power transformers: bushings, windings (active part), and the on‑load tap‑changer (OLTC)—the components associated with most transformer failures according to industry guidance and reliability studies.

 

We then take the next step: using ETOS® Asset Intelligence to fuse data from all sensors and operational events into a consistent, holistic view of transformer health. The analytics layer correlates signals, identifies likely fault causes, and provides clear recommended actions.

 

You’ll leave with a monitoring blueprint, example thresholds and event interpretations, and tips for moving from individual units to fleet‑wide condition awareness—so you can improve uptime, prioritize interventions, and make better asset decisions throughout the energy transition.
