ABOUT THE LESSON
World class DGA experts discuss the key questions about DGA for transformers
The discussion will include:
– In-house DGA tests by a lab or a portable device: time and precision issues.
– Practice of DGA at emergency (after Buchholz alarm, online monitoring alarm, trip, any kind of alarm)
– Sampling issue, sealed syringes versus bottles and ampules; effects on accuracy
– Online DGA devices: one or two gases versus four or more gases; diagnostic, benefits for user (continue or stop the operation)
– Extraction and detection of gases: gas chromatography vs. spectroscopy, maintenance issues
– Interpretation and diagnosis: gas limits, the most accurate diagnostic method, the future of artificial intelligence and machine learning tools
