  • Abstract
    This paper describes usage of several condition monitoring techniques to evaluate the failures and failure modes of generator stator insulation. Authors have included several case studies of insulation weaknesses and failures of generators in Sri Lanka. Author´s recommendations to use DC ramp test for the evaluation of failures of generators and effect of moisture in stator insulation, are highlighted.
