A METHOD TO DIAGNOSE MECHANICAL FAULTS IN A TRANSFORMER

摘要

ABSTRACT A METHOD TO DIAGNOSE FAULTS IN A TRANSFORMER A method to diagnose mechanical faults in a transformer is provided. The method comprises the steps of obtaining parameters associated with the transformer by a test instrument connected to at-least one winding of the transformer, the parameters include at-least one of frequency (Fq), magnitude (MdB); resonance at frequency (Rfq); turns ratio (TR); tap position (Tprq); winding resistance (Wr) and magnetic balance (MB) of the transformer; analysing at-least one of the parameters to determine operating condition of transformer; and identifying at-least a core related fault or a winding related fault or a tap winding related fault or a lead related fault of the transformer based on the obtained parameters in response to determining that a fault condition exists in the transformer.
