E-lesson: DGA course – e-lesson #12 – Implementing DGA to distinguish between real faults and non-critical failures
Hosted by: Marius Grisaru / Free
The Big Question: When should one recommend taking a transformer out of service (based on DGA)? Inspired by a paper presented at ASTM Conference, Seattle ,1999.
- transformer fault severity from DGA evaluation, real cases of avoiding fault alarms and disconnected transformers just before a critical failure,
- levels of total combustion gases and trends versus fault severity,
- advanced diagnostic approach emerging from particular individual, practical and theoretical practice – an old but gold diagnostic method,
- real cases inspected after DGA evaluation by different methods.
Keywords: DGA diagnosis, real cases, expertise, health evaluation
