摘 要：正 This paper investigates the noise source and counter-measure of mold transformer radiated high *** result of the impact hammering test forthe core of the transformer ascertains the core resonanceby harmonics of the line frequency and the high noise canbe reduced to avoid the core resonance by the changingtorque strength of the tie *** reason that the noise ofV-phase is higher than U and W-phases in the normalcondition presents by evaluating the magnetic force ofeach phase.
