  • REDUCTION OF CONVERTER TRANSFORMER FAILURES

    eventually result in the failure of the converter transformer. The harmonic leakage fluxes cause thermal problems in the converter transformer which may lead to its failure. Grant and McDermid stated that a converter transformer shows signs of insulation degradation due to thermal aging after a few dec-ades of normal operation.[13]
