| Abstract: | In order to meet the need of site oscillating impulse withstand voltage test for oil filled transformer, based on Marx loop theory, according to the structure characteristic of the transformer,puts forward the method of bringing test voltage and test connection. The simulation calculation and test shows that to connect inductance coil in the Marx loop which constitute the impulse voltage generator with double exponential waveform, can bring the oscillating impulse voltage waveform accord with IEC 60060-3 standard. |
