The chromatographic analysis method for detecting dissolved gases in transformer oil is essential in discovering latent faults in oil-filled electrical equipment as early as possible. It can detect internal faults of equipment, predict the development trend of faults, and avoid equipment damage and unplanned power outages; according to the harmfulness of the fault, the importance of the equipment, and the load requirements, reasonable fault handling measures are formulated to ensure that the equipment is not damaged. This is an essential means of supervising and ensuring the safe operation of equipment.

Optimizing the transformer oil chromatography testing process is essential for improving testing efficiency, enhancing result accuracy, and ensuring equipment safety. The following sections detail how to optimize this process from sampling operations, sample preservation, degassing methods, equipment maintenance and calibration, data analysis, to result validation.

Transformer oil chromatograph is an important analytical tool that uses chromatography to quantitatively and qualitatively analyze the gas components dissolved in transformer oil. For power generation and supply companies, this instrument is a key means to monitor whether oil-filled power equipment has potential overheating, discharge and other faults, ensuring the safe and stable operation of the power grid.
