TRANSFORMERS· PDF file1. Magnetizing current in Y-phase was found to be 1.06 A which is very high as compared to 3.6 mA in R-ph and 3.5 mA in B-ph. Also, very low voltage (0.506 V) was observed in Y-ph in magnetic balance test when 231 V was applied on R-phase which indicates problem in Y-phase winding. DGA of oil indicated high concentration of Hydrogen (H2-2064ppm)),
