METHOD FOR DETECTION OF DEVELOPING DEFECTS IN HIGH-VOLTAGE POWER TRANSFORMERS BY RESULTS OF THE ANALYSIS OF DISSOLVED OIL GASES

METHOD FOR DETECTION OF DEVELOPING DEFECTS IN HIGH-VOLTAGE POWER TRANSFORMERS BY RESULTS OF THE ANALYSIS OF DISSOLVED OIL GASES

The article describes a method for detecting developing defects in high-power oil-filled transformers, based on the results of analysis of dissolved gases in oil. It has been found that an early diagnostic sign of development of ionization processes of aging and thermal degradation in transformers’...
