Acknowledgments this report accounts for the thesis work “analysis of partial discharge in oip bushing” performed between february 2011 and august 2011 i would like to say thanks to mohammad gaffarian for his help in setting the partial discharge measurement setup in high voltage laboratory documents similar to partial discharge tesis. Pre-breakdown phenomena in transformer liquids have been extensively investigated the published work can be broadly categorised into streamer and partial discharge (pd) studies, with the former focusing on physical nature and the latter being more relevant to industrial applications. Partial discharge (ie breakdown voltage located at a point) also depends on the pressure, temperature, polarity of the pd, the involved gas, and to a lesser extent, humidity.
