The DVLS Transformer Oil Gas Analyzer (TOGA) determines the dissolved gas content in the transformer oil, which provides the diagnostic information on the current and future stability of the transformer. The DVLS TOGA analyzer complies with IEC 60567 & ASTM D3612-C to extract and measure gases dissolved in electrical insulating oil and to identify the individual gas component extracted.
The DVLS TOGA Analyzer uses the Agilent 8890 GC configured with a Headspace sampler and the innovative Revolving Table and the Degassing Unit developed by Sea Marconi.
The Revolving Table is a tool designed by Sea Marconi to improve the preparation steps for insulating oil samples for the Dissolved Gas Analysis (DGA) with the gas chromatography technique in the headspace. This sample preparation tool complies with IEC 60567:2015 as Oil-filled electrical equipment for the sampling of gases and analysis of free and dissolved gases.
The Degassing Unit optimizes the degassing process during the preparation of gas in oil standards for Dissolved Gas Analysis (DGA).
Since the presence of the dissolved gases reveals the faults of a transformer, these gases are also known as Faulty Gases. Examples of the faulty gases are:
Several test methods are available to measure the dissolved or faulty gases in transformer oil:
