Transformer monitoring & diagnostic system (TMDS) market was valued at $2.1 billion in 2025 and is projected to reach $3.8 billion by 2035, growing at a CAGR of 6.3% during the forecast Period (2026-2035). Enhanced gas analysis in transformer health monitoring improves detection of air leaks and insulation degradation, boosting the adoption of TMDS by utilities and industrial operators for real-time insights into transformer conditions and driving market growth. For instance, in April?2025, Vaisala introduced an updated version of its Optimus OPT100 dissolved gas analysis (DGA) monitor with added oxygen and nitrogen measurement parameters. This enhancement improves early detection of air leaks and insulation degradation in power transformers, helping reduce unplanned outages and extend asset life.
