DGA (Dissolved Gas Analysis)

Dissolved Gas Analysis (DGA) is a diagnostic technique used to evaluate the condition of electrical transformers and other equipment by analyzing gases dissolved in their insulating oil. When electrical equipment experiences stress, deterioration, or faults, it produces specific gases like hydrogen, methane, or carbon monoxide. Measuring these gases helps identify potential issues early, such as overheating, arcing, or insulation breakdown, enabling maintenance teams to prevent failures and extend the asset's lifespan. DGA provides valuable insights into the equipment's health without invasive inspection, making it a vital tool in condition monitoring.
