The escalating global focus on greenhouse gas reduction has placed sulfur hexafluoride (SF6) under intense scrutiny. With a global warming potential 23,500 times that of CO2, the escape of this gas into the atmosphere is a critical environmental concern.

Ethylene (C₂H₄) is a critical indicator gas in transformer oil analysis, signaling severe operational stress within power transformers. Generated through excessive heat exposure—typically above 500°C—ethylene results from the degradation of transformer oil and solid insulation mat
