in the transformer so that the operating temperature increases, leading to deterioration of the insulation and a potential reduction in lifetime. As a result, it is necessary to reduce the maximum power load on the transformer, a practice referred to as de-rating, or to take extra care in the design of the transformer to reduce these losses.

  • Transformer Evacuation Systems | oil filtration machines | Nach

    Transformer Evacuation System. Vacuum is drawn in transformer tank with aid of transformer evacuation system to remove moisture and gases from insulation/oil. Alternately during commissioning of transformer, nitrogen is evacuated with transformer evacuation system before new oil filling or oil alteration in transformers. Transformer evacuation is a wet process which necessitates proper moisture extraction before its entry into vacuum pump.

  • Significance of CO2/CO ratio in - Transformers Magazine

    AbstractIntroductionCarbon Monoxide and Carbon Dioxide in Transformer OilCase 1According to the literature, the ratio of carbon dioxide and carbon monoxide (CO2/CO) for a transformer with a healthy cellulose insulation system should be between 3 and 11. If results of the dissolved gas analysis (DGA) of oil from transformers in service give the ratio value of CO2/CO less than 3, it means that the cellulose insulation is degrading rapidly. What is the meaning of this ratio if it is high; say greater than 15 or 20? Keywords:carbon monoxide, carbon dioxide, ratio, dissolved gas analysis
