  • Practical Experience Gained from Dissolved Gas Analysis

    Dissolved gas analysis (DGA) of oil samples is probably the most effective means of monitoring the condition of oil-filled electrical equipment such as transformers, for several reasons. Firstly, nearly every possible fault generates one or more gases arising from the consequential increased degradation of

This procedure is called Dissolved Gas Analysis (DGA). For many years, the method of analyzing gases dissolved in oil (DGA) has been used as a tool for transformer diagnostics. The method has several

  • Gas insulated power transformers: A growing technology

    Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is

  • Dissolved Gas Analysis in Transformer Oil

    Mar 01, 2015The Dissolved Gas Analysis (DGA) is a chemical test rather than an electrical test. It does not suffer from electrical interference and can be done without de - energization of the transformer. The cost of each DGA is relatively inexpensive. All these factors make DGA a powerful tool in the preventive maintenance of transformer.

  • Assessing Remnant Life of Transformer based on Furan

    insulation has deteriorated. As the Transformer was in service for more than 31 years, it was necessary that we should evaluate the remnant life of the solid insulation and plan further suitable action for its replacement / refurbishment. We decided to carry out the DP test to ascertain the extent of degradation of the paper insulation.

  • 2016 Transformer Oil Sampling and Analysis

    ASTM D3612 - Dissolved Gas Analysis Gas analysis is based upon the fact that both electrical insulating oil and cellulosic insulation break down under abnormal thermal or electrical stress. The results of these stresses are both volatile and non-volatile gases, known as fault gases. Gas analysis is the technique that identifies fault gases, relates their quantity, generation rate and

    Oct 27, 2020Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil.It is also referred to as a DGA test. Whenever a transformer undergoes abnormal thermal and electrical stresses, certain gases are produced due to the decomposition of the transformer oil. When the fault is major, the production of decomposed gases are significant and they get collected in a Buchholz relay.
