Dissolved gas analysis (DGA) of transformer oil is a process used to detect and measure gases that are dissolved in the oil. These gases are generated by thermal or electrical stress inside the transformer. DGA helps identify potential issues such as overheating, arcing, or partial discharges, enabling early intervention and maintenance to prevent transformer failures.
