Abstract

Electric response of nanocomposite industrial materials has been
investigated for all possible causes and effects of the interphase region
on a variety of complex composite systems by using Interphase Power
Law IPL model. Thus, this paper investigates the effective dielectric
response of nanocomposite industrial insulation materials and effects of
the interphase region on a variety of complex composite systems.
According to the statistical approach of failure in polymeric insulators,
that leads us to predict the procedures and mechanisms of failures which
occur within insulating materials, this paper illustrates the failure
statistics of a life model for ac electrical aging of nanocomposite
insulation industrial materials which depicts the mechanisms of
electrical breakdown under high voltage electric fields by advanced
simulation model program. Case studies are used to illustrate the way
and mechanisms which mechanistic features which can be related to the
parameters of the failure statistic. Realized lifetime of insulation
materials can be evaluated by means of this model. Aging of polymeric
insulators has been examined through various high voltage electric
fields, so the possibility of predicting the lifetime of individual specimens
has been succeeded.
