Dissolved gas analysis (DGA) has been used to classify the type and severity of faults in transformers. The method commonly used to identify severity is to measure the total fault gas concentration and its rate of change, without regard to the relative concentrations of individual gases. Thermodynamic analysis indicates that the energy required to form gases increases in the order CH<sub>4</sub> <; C<sub>2</sub>H<sub>6</sub> ≤ CO ≤ C<sub>2</sub>H<sub>4</sub> <; H<sub>2</sub> ≪ C<sub>2</sub>H… CONTINUE READING
