Abstract
According to the physical characteristics of oscillating impulse voltage (OIV) specified in IEC 60060-3 standard, a numerical method is proposed for producing OIV by actual equivalent circuit. Through theoretical analysis of the circuit model, analytical expressions of several important parameters of the waveforms are obtained. Also, influences of load range upon waveform parameters are discussed. The results indicate that by changing the circuit elements, OIV waves can be generated to meet the engineering design requirements for different load degrees, The difference between the numerical solution of waveform parameter expression and the analytical solution with model is small under model parameters have been identified. Therefore this method provides a theoretical basis for on-site testing OIV generator.
