Lightning characteristics and standard impulse waveform are related to each other. But the lack of realization about the relation between them would make the solution to produce better protection against lightning surge becomes harder. Natural lightning surge waveform has been compared to standard impulse waveform as evidence that there have similarity between them. The standard impulse waveform could be used to test the strength of electrical equipment against the lightning. Therefore designing and simulating the impulse generator are the purpose of this project beside to get better understanding about lightning characteristics. This project aims to develop an impulse generator circuit using OrCAD PSpice software to produce a lightning waveform according to IEC61000-4-5 standard. For this reason, Marx generator has been used as the main principle of the design with some parameters and components modifications. The output waveform from simulation was compared to IEC61000-4-5 surge standard, and the values in the developed circuit were adjusted so that the characteristics of the waveform are in acceptable limits. As the result, the correct lightning waveform in the form of voltage versus time has been generated from an impulse generator circuit OrCAD PSpice software. In the conclusion standard impulse waveform has been fulfilled and the value of each component used truly influence the resulted waveform. The lightning waveform can be used in further research such as determination of V-I characteristics of surge arresters and other lightning protection purposes.
