Experimental verification of distribution transformer model under lightning strokes

In this paper, the distribution transformer model under lightning impulses introduced by Piantini at no load conditions is investigated. This model is modified where this modification takes more than one resonance frequency into consideration during the model parameters calculation. Therefore, the frequency response of the simulated transient voltage is improved comparing with Piantini model. The verification of the modified model is carried out through the comparison between the experimental and simulation results, in which the time domain simulation is carried out using ATP/EMTP while MATLAB is used to identify the model parameters. The comparison showed a good agreement between the simulation and experimental results.
