Abstract

In this paper, some non-standard impulse voltage waveforms are generated through simulation platform and fed to the oil-paper insulation model to analyse the responses. Effect of non-standard lightning impulse voltage is detrimental for electrical insulation. Due to this reason after manufacturing of electrical equipment, it undergoes through a lightning impulse voltage test of standard waveform (1.2 × 50) μs. However, it has been observed that natural lightning does not follow the standard impulse voltage waveform. The knowledge of insulation behaviour upon application of non-standard impulse is essential for design engineers. Hence, transformer’s oil-paper insulation has been modelled by Extended Debye Model (EDM) in simulation for the realization of the standard and non-standard lightning impulse (NSLI) response. The effect of temperature variation on impulse response of EDM has also been incorporated.
