| Summary: | This paper presents the performance of polymeric
and non-polymeric insulation material in contaminated
condition. The purpose of this study is to determine the accuracy
of analysis technique on the performance these types of insulation
against its tracking and erosion. Polypropylene and glass are
selected as polymeric and non-polymeric material. Tracking and
erosion test complying with BS EN 60587-2007 are conducted,
then leakage current frequency components is used as a
diagnostic tool for their surface condition monitoring and
degradation severity. The analyses of leakage current are based
on frequency domain and time-frequency representations are
conducted. From the results, the surface condition of polymeric
insulation material state can be classified accurately by using
spectrogram compared to Fast Fourier Transform. It also proved
that the performance of tracking and erosion of glass is better
than polypropylene material. |
