DGA technique for identifying the inner incipient faults inside the electric transformer

Mahesh lamba, Yogita rathi, vikrant singh


Incipient fault prognosis of an energy transformer is significantly prompted by the circumstance assessment of its insulation machine oil and/or paper insulation. Dissolved gas-in-oil evaluation (DGA) is one of the maximum powerful techniques for the detection of incipient fault condition within oil-immersed transformers. The transformer records have been analyzed using key gases, Doernenburg, Roger, IEC and Duval triangle strategies. This paper introduce a MATLAB application to assist in unification DGA interpretation techniques to analyze the accuracy of these techniques in decoding the transformer condition and to provide the excellent notion for the sort of the fault inside the transformer based totally on fault percentage.
