What is transformer oil degasification and why is it important?

Transformer oil degasification is the process of removing dissolved gases, primarily hydrogen, methane, and ethane, from transformer oil. This is crucial because the presence of these gases can indicate insulation breakdown or overheating, leading to reduced transformer efficiency and potential failure. Effective degasification enhances the dielectric strength of the oil, prolongs transformer life, and ensures reliable operation by maintaining optimal insulation properties and minimizing the risk of electrical arcing.
