  • Abstract
    The results of this study showed that substituting a partially conducting polyester filler material for insulating polyester filler material can reduce the increase in loss tangent with increasing voltage (i.e. “tip-up”) observed in bars simulating generator coils. Polypyrrole-coated polyester performed better than the conventional insulating material and polyaniline-coated polyester
