All about DGA - 5 critical considerations for getting the most out of your online DGA
and Jan 22, 2026
Join us live to explore the most important factors for successfully implementing and optimizing online Dissolved Gas Analysis (DGA) monitoring systems.
Together with Vaisala's Senja Leivo and Lee Doyle, we focus on practical insights that help ensure early fault detection and prevent costly transformer failures. The webinar covers the whole range from initial installation planning through ongoing data analysis and offers you valuable insights and practical tips for implementing DGA monitoring for enhanced transformer reliability, optimizing maintenance planning, and supporting effective operational decision-making.
Key takeaways:
- Location and setup – best practices for equipment positioning, oil pipe quality, environmental factors, and maintaining clean, dry installation conditions.
- Transformer selection – which transformers benefit most from continuous monitoring that maximizes grid reliability and asset protection.
- Alarm limits – how to establish meaningful threshold values that deliver timely alerts while avoiding unnecessary false alarms.
- Data interpretation – trending analysis techniques, diagnostic methods, and how to correlate gas measurements with transformer operating conditions to support better decision-making.
- Live Q&A session – get answers direct from the experts. Your questions are welcome both ahead and during the webinar.
