A dissolved gas analyzer (DGA) is an essential diagnostic instrument for monitoring the health of power transformers by detecting and quantifying gases dissolved in insulating oil. These gases—hydrogen, methane, ethylene, acetylene, carbon monoxide, and others—form due to thermal and electrical faults like overheating, partial discharges, or arcing. Early identification prevents catastrophic failures, extends transformer life, and ensures grid reliability. Technologies include gas chromatography (dominant for accuracy), photoacoustic spectroscopy, and others. Devices range from portable units for on-site testing to online systems for continuous monitoring, with extraction methods like vacuum, headspace, or stripper column. DGAs are vital in utilities for predictive maintenance amid rising power demands.
