Leading Players: Top 5 players in this market include Doble/Morgan Schaffer, Qualitrol, GE Kelman, Vaisala, Siemens Energy, which collectively held a market share of 48% in 2025.
The dissolved gas analyzer (DGA) market is evolving from periodic oil-sampling workflows toward continuously connected diagnostic programs. Demand is increasingly shaped by utilities' need to identify thermal faults, electrical discharge, arcing, and insulation deterioration before transformer failures disrupt grid operations, while software-enabled analysis broadens the value proposition beyond instrument hardware.
GMI Analyst View
Based on our discussions with equipment manufacturers and utility operators, the dissolved gas analyzer market was valued at USD 0.5 billion in 2022, establishing a consistent growth foundation from which accelerating grid modernization investment and the broad formalization of condition-based maintenance programs across major utility markets have driven steady annual expansion through the 2025 base year.
Dissolved Gas Analyzer (DGA) Market Trends, Growth Drivers & GMI Forecast Outlook
The market outlook rests on a widening installed base of critical transformer assets and a procurement shift toward earlier fault detection. Grid expansion, renewable interconnection, and reliability obligations are supporting online monitoring adoption, although deployment speed remains contingent on diagnostic talent availability and utilities' willingness to fund fleet-wide digital integration.
Key Drivers
*Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.*
Grid investment changes the commercial timing of DGA procurement. Monitoring is increasingly specified alongside transformer and substation projects, allowing utilities to integrate communications, asset-management workflows, and alarm protocols before energization rather than treating diagnostics as a corrective retrofit. This favors suppliers able to support installation, commissioning, and ongoing data interpretation across large fleets.
Renewable generation adds a particularly important demand channel because collector and generator step-up transformers experience variable loading profiles and are often located where unplanned intervention is costly. The expanding large-transformer pipeline is therefore broadening the set of assets for which continuous surveillance is justified, especially where replacement lead times and outage exposure make early warning operationally valuable.
IEC 60599 and IEEE C57.104 reinforce that shift by providing a common diagnostic language for interpreting gas patterns and escalation priorities. Their influence reaches beyond laboratory analysis: utilities can standardize asset-health decisions across dispersed fleets, while vendors can embed recognized diagnostic logic into connected platforms. Work to adapt DGA practices for renewable-energy transformer fleets further extends this framework into newer asset populations [6]NETA World Journal. "Distributed Energy Transformer Dissolved Gas Analysis Standards Development." netaworldjournal.org.
Key Restraints
*Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.*
The skills constraint is not simply a staffing issue; it affects whether a utility can translate gas measurements into credible maintenance action. Multi-gas diagnostics require trend evaluation, operating-context awareness, and escalation discipline. Where those capabilities are scarce, buyers may delay online-platform rollouts, narrow deployments to the most critical assets, or favor suppliers that provide managed interpretation and automated decision support.
Capital requirements create a parallel adoption divide. A continuous system requires more than an analyzer: it must be installed into the transformer environment, connected to utility data architecture, and supported through calibration, cybersecurity, and workflow integration. This keeps the strongest near-term economics in high-consequence transmission and generation assets, while portable and laboratory-based approaches remain relevant where periodic assessment is operationally sufficient.
GMI Analyst View
We view the forecast as a reliability-led adoption cycle rather than a simple instrumentation replacement cycle. The decisive commercial question is how effectively suppliers convert monitoring data into usable maintenance decisions for utilities that lack specialist diagnostic capacity. Vendors combining robust hardware with intuitive analytics, service support, and integration capability should be best positioned to extend adoption beyond the most critical transformer classes.
Dissolved Gas Analyzer (DGA) Market Segment Analysis
By Product Type
Online/Continuous DGA Systems
Online/continuous DGA systems held a 55% share of the dissolved gas analyzer (DGA) market in 2025 and are projected to generate USD 0.8 billion by 2035.
