In power systems, ‘Power Transformer is one of the very important components in the power system. Anyfailure of the power-transformer results in widespread and serious disturbances. Also at higher voltage levels, it is notpractical to have stand-by units of large and very expensive transformers. Thus transformer failures cause a longduration power outage as well as large financial losses.In view of the above, transformer failures have been widely investigated but there are still many unexplained failures.Therefore in this paper an attempt is made to understand the behaviour of transformer for lightning and fast risingrepresentative switching surges of double exponential nature waveforms. Different surges of 1kV magnitude aregenerated in the laboratory and are applied to a custom built transformer winding model having 160 turns which ispartly interleaved. Studies are carried out for lightning impulses and fast rising switching impulsesmentioned above.
