Stray gassing in transformer oil refers to the unintended generation of gases within the oil, which can compromise the performance and reliability of the transformer. This phenomenon typically results from the decomposition of the oil due to overheating, electrical discharges, or contamination. Stray gassing produces gases like hydrogen, methane, and ethylene, which can accumulate and lead to pressure build-up within the transformer, potentially causing insulation breakdown, reduced cooling efficiency, and even hazardous conditions if left unchecked. Monitoring for stray gassing is crucial for maintaining optimal transformer function, ensuring the longevity of the equipment, and preventing failures that could disrupt power supply systems. Regular analysis of transformer oil can help identify the presence of stray gassing and facilitate timely corrective actions. Proper cleaning, regeneration, and maintenance routines for transformer oil are essential to mitigate these risks effectively.
