High ethane in transformer oil
Web1 de jan. de 2024 · Abstract: Methane is one of the indicative gases in power transformer oil, and the detection of methane dissolved in oil with high accuracy is of great importance for dissolved gases analysis and fault diagnosis inside power transformers. Based on the Beer–Lambert spectral absorption law, dissolved methane detection with tunable diode … Webin transformer insulating oil may be used directly and trended to evaluate the thermal history of the transformer internals to suggest any past or poten-tial faults within the transformer. After samples have been taken and analyzed, the first step in evaluating DGA results is to consider the con-centration levels (in ppm) of each key gas.
