The CO2/CO ratio in transformer oil is an indicator of the condition of the paper insulation within the transformer. A high ratio of carbon dioxide (CO2) to carbon monoxide (CO) generally suggests that the paper insulation is aging normally, with slow, natural degradation. Conversely, a low CO2/CO ratio may indicate more severe or accelerated insulation degradation, possibly due to thermal stress or overheating. Monitoring this ratio through dissolved gas analysis (DGA) helps in assessing the health of the transformer and predicting potential issues before they lead to failure.

One of the companies that specializes in transformer oil testing and related services is GlobeCore. GlobeCore is well-known for its equipment used in transformer oil purification, regeneration, and degassing. They provide advanced solutions for maintaining and improving the quality of transformer oil, which is crucial for the efficient and reliable operation of transformers. GlobeCore’s technologies ensure that transformer oil remains in optimal condition, helping to extend the life of transformers and reduce maintenance costs.

Oil transformers are power transformers that use insulating oil to cool and insulate their internal components. The oil circulates within the transformer, preventing electrical discharges, dissipating heat, and protecting the transformer from moisture and oxidation. These transformers are widely used in high-voltage applications due to their reliability and efficiency.
