The oscillation impulse voltage test of power equipment has high efficiency and is easy to implement in field. The volume of generation equipment can be reduced by using inductive principle to generate the operate impulse voltage. The oscillation impulse voltage test technology for power transformer is studied in this paper based on inductive principle. A 110 kV transformer is used to carry out the field test based on theory analysis. The simulation is carried out using transformer parameters. The experiment and simulation results show that the oscillation impulse voltage waveform that meet the requirement of standard can be generated according the method provided by this paper.
