Global market for dissolved gas analyzers has been covered under the scope of this report. Dissolved gas analyzers are utilized for identifying the incipient faults occurring in power transformers and other oil-filled electrical equipments. When subjected to high thermal and electrical stress, the mineral oil inside a power transformer decomposes, leading to generation of gases such as carbon mono-oxide (CO), carbon di-oxide (CO2), methane (CH4), acetylene (C2H2), ethylene (C2H4) and hydrogen (H2) among others. The gases generated vary upon the fault occurring in the transformer. The investigation of these gases, using a dissolved gas analyzer, can endow with information on the types of faults which might occur or are occurring in the transformer. Additionally, these analyzers allows for a low cost testing of dissolved gases in mineral oil of power transformers, and thus help in calculating effective maintenance and replacement strategies of these expensive transformers.
The global dissolved gas analyzer market is primarily driven by the growth in utility (power transformer) and industrial infrastructure investments. Additionally, various regulations pertaining to the environment and power industry, which are being enacted by different government agencies of different countries, the European Commission’s (EC) Ecodesign regulation, are also positively impacting the market for dissolved gas analyzers. The increasing adoption of online DGA (dissolved gas analysis) is another significant factor which is helping to drive the dissolved gas analyzer market forward. Considering all these positive impacts, demand for dissolved gas analyzers are set to rise during the forecast period from 2014 to 2020.
The global dissolved gas analyzer market has been segmented into four regions: North America, Europe, Asia Pacific and RoW (Rest of the World). In 2013, Asia –Pacific held the largest market share of global dissolved gas analyzer market. Dissolved gas analyzer market in Asia Pacific is driven by rising application of dissolved gas analyzers in large power transformer base and rising penetration of online DGA analysis. North America was the second largest market, followed by Europe.

The dissolved gas analyzer market in North America is driven by demand for increasing the lifespan of aging power transformers and detection of fault gases in newly installed transformers among others. The dissolved gas analyzer market in Europe is driven by demand for increasing the lifespan of aging power transformers and rising environmental concerns about power generation among others.
The global dissolved gas analyzer market, by extraction types, can be divided into four segments such as vacuum extraction or rack method, head space extraction, the stripper column method and others (multiple gas extractors). As of 2013, vacuum extraction method held the largest market share of global dissolved gas analyzer market. Vacuum extraction method is widely used due to its simplicity, low cost of ownership and lack of awareness among customers about other extraction methods.
