See other companies with research projects supported by PIPE ProgramPower transformer failures have a high impact on power supply, result in high replacement cost, and affect quality indices. To assist in the prevention of catastrophic failures it is of great importance to monitor the operational state of the transformers by both measuring the volume of combustible gases present in the internal atmosphere and the oil level. Currently, "Buchholz" gas relay…
The SMCT manages the power transformer oil moisture (in the most important Electrical System Substation equipment, about 56% of the total cost) by removing the internal humidity trough a dry atmosphere of nitrogen. Moisture alongside oil oxidation has been the main factor of degradation of transformer´s insulation, accelerating its wear and dramatically reducing its load capacity and life…
