A dissolved gas analyzer (DGA) is a diagnostic instrument used to detect and measure gases dissolved in transformer insulating oil. These gases—such as hydrogen, methane, ethylene, acetylene, carbon monoxide, and carbon dioxide—form due to thermal and electrical stresses, indicating potential faults like partial discharges, arcing, or overheating. Early detection prevents transformer failures, reduces downtime, and extends equipment life. Technologies include gas chromatography (dominant for accuracy), photoacoustic spectroscopy, and others. Devices range from portable for on-site testing to online systems for continuous monitoring, with extraction methods like vacuum, headspace, or stripper column. DGAs are essential for utilities in predictive maintenance amid rising power demands.

Market Overview

The North America dissolved gas analyzer market is projected to grow at a CAGR of 7.4% during the forecast period of 2023–2030. This expansion is driven by increasing investments in power infrastructure, heightened focus on transformer reliability, and surging electricity consumption from urbanization and electrification trends. While specific base-year values are detailed in the full report, the market benefits from technological advancements enabling real-time fault detection and grid protection.
