What happens after a CIGRE paper is presented? Join us for a practical webinar that brings the research into the field.
Based on the poster presented at the CIGRE Paris Session 2026, this webinar explores how partial discharge was successfully detected and localized on a high-voltage transformer bushing using OptiFinder and fiber optic acoustic emission sensors. We’ll walk through the project, explain the monitoring approach, demonstrate the localization results, and share practical lessons learned from real-world implementation.
Whether you attended CIGRE or couldn’t make it to Paris, this webinar offers the key takeaways from the poster presentation, enriched with practical insights, expert commentary, and guidance on applying fiber optic acoustic PD monitoring to improve asset diagnostics and maintenance decisions.
