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.

The purpose of DGA in transformer oil is to monitor the health of the transformer by detecting early signs of internal faults, such as overheating, arcing, or insulation breakdown. By analyzing the types and concentrations of dissolved gases, DGA can provide valuable insights into the condition of the transformer, allowing for preventive maintenance and reducing the risk of failure.

Polychlorinated biphenyls (PCBs) were once commonly used in transformer oils due to their excellent insulating properties. However, due to their toxicity and environmental hazards, the use of PCB-containing oils has been banned or restricted in many countries. Transformers that once used PCB oils are being phased out or retrofitted with safer alternatives.
