In the electric power industry, transformer oils and fibrous insulating materials age and decompose due to exposure to moisture, oxygen, heat, and the catalytic effects of materials like copper and iron.
The gases produced are mostly dissolved in the oil, but their rate of generation is quite slow.
However, when initial faults exist inside the transformer or when new fault conditions form, the rate and volume of gas production become significantly noticeable.
Most initial defects will show early signs, thus, appropriate analysis of gases generated by the transformer can detect these faults.
As the transformer ages, initial faults may develop Certain combustible gases in the oil can be precursors to internal faults,potentially lowering the flash point of the transformer oil and causing early failure.
High-precision laser methane/ethyne/ethylene gas analyzers use tunable laser absorption spectroscopy technology and advanced detection algorithms.
They offer a resolution up to 1ppm for quantitative analysis of trace gases produced in transformer oil, thereby eliminating potential hazards.
Compared to traditional gas chromatography, TDLAS technology offers advantages such as higher sensitivity, strong anti-interference capabilities, and stable reliability.
