N2 - Oil-immersed transformers are essential components of modern power systems, with their stable operation being directly linked to the overall safety and reliability of the grid. However, the distance between the online monitoring device and the fault oil reservoir, coupled with the complex structure of oil pipelines, introduces uncertainties. o address the aforementioned challenges, this study conducts a detailed investigation into the effects of various pipeline configurations (length, diameter) on the concentration of characteristic dissolved gases. Through a series of controlled parallel experiments, one independent variable was systematically varied while the remaining variables were held constant. Results confirm that gas concentration fluctuations across all test cohorts remained within statistical tolerance limits. The consistent trajectory of fitted curves demonstrates that variations in hose length and internal diameter exert statistically insignificant effects on dissolved gas content.
