Market Segmentation
➡By Type
Single-Gas Analyzers: Devices designed to monitor one specific dissolved gas, often used for focused fault detection.
Multi-Gas Analyzers: Instruments capable of detecting multiple gases simultaneously, providing a comprehensive assessment of transformer condition.
➡ By Power
100-500 MVA: Common transformer capacity range in utilities and industrial settings; DGA solutions are optimized for this range.
501-800 MVA: Mid-to-high capacity transformers, requiring robust monitoring due to higher fault risk.
801-1200 MVA: Very large transformers where precise, high-sensitivity DGA is critical for operational reliability.
➡ By Extraction Type
Vacuum Extraction (Rack Method): Uses vacuum to extract dissolved gases from oil; widely used due to high accuracy and non-destructive sampling.
Headspace Extraction: Agitates and heats oil to release gases into a vial’s headspace; beneficial for rapid analysis and reduced sampling error.
Stripper Column Method: Uses a column to strip gases from oil; suitable for laboratory or high-precision applications.
Other Methods: Includes newer or hybrid extraction techniques, such as membrane-based extraction, depending on vendor technology.
