Near-infrared dual-gas measurement of ethylene and ethane based on Noise-Suppressed NMF

Dissolved gas analysis (DGA) is a critical method for transformer fault diagnosis. Medium-to-high-temperature thermal fault is a key focus in transformer condition monitoring, with its characteristic gases primarily dominated by ethylene (C₂H₄) and ethane (C₂H₆). Traditional detection methods based...
