What is the significance of the CO2/CO ratio in transformer oil?

The CO2/CO ratio in transformer oil is significant as it serves as an indicator of the oil’s condition and the health of the transformer itself. A higher CO2/CO ratio may suggest the presence of thermal oxidation, which can lead to insulation breakdown and ultimately transformer failure. Monitoring this ratio allows for early detection of potential problems and aids in decision-making regarding oil regeneration, cleaning, or replacement to ensure optimal transformer performance and longevity. Understanding the CO2/CO ratio transformer oil is crucial for maintenance schedules and enhancing the reliability of electrical systems.
