Gas laws for transformer dissolved gas analysis DGA starting from the ideal gas equation of state

Transformers Magazine
Dissolved gas analysis (DGA) is a non-invasive screening and diagnostic method for liquid-insulated power transformers. The basic gas laws underlying common calculations used for DGA interpretation are derived and explained from the ideal gas equation of state.
