Standard Test Method for Analysis of Gases Dissolved in Electrical Insulating Oil by Gas Chromatography

Importancia y uso:

5.1 Oil and oil-immersed electrical insulation materials may decompose under the influence of thermal and electrical stresses, and in doing so, generate gaseous decomposition products of varying composition which dissolve in the oil. The nature and amount of the individual component gases that may be recovered and analyzed may be indicative of the type and degree of the abnormality responsible for the gas generation. The rate of gas generation and changes in concentration of specific gases over time are also used to evaluate the condition of the electric apparatus.

Note 1: Guidelines for the interpretation of gas-in-oil data are given in IEEE C57.104.
