  • Guest Editorial | Understanding Dissolved Gas Analysis

    Since normal gas generation varies with transformer design, loading, and the type of insulating material used, general gassing rates are used for all transformers to define abnormal behavior. Typical gases that appear in transformers are hydrogen (H 2 ), methane (CH 4 ), ethane (C 2 H 6 ), ethylene (C 2 H 4 ), and acetylene (C 2 H 2 ).

  • Transformer gaskets | TD Guardian Articles | USA

    The paper insulation is strongest when the transformer is new and immediately begins to age and weaken as the transformer is loaded. The aging is a due to a combination of heat, moisture and time. To date, the industry has yet to figure out how to make transformers 100% efficient where there would be no loss and therefore no heat generated.
