The Transformer Oil Gas Chromatograph is a precision analytical device that uses chromatography to determine the component content of dissolved gases in transformer oil. It serves as an essential diagnostic tool for power generation and supply enterprises, enabling the detection of latent faults such as overheating and discharge in oil-filled power equipment.
