To measure the current impulses before a discharge process in an insulation material is completed a proposed system has been built theoretically. The blocks in the system have been studied by going through relevant sources and meetings with the supervisor of the project and new ideas have been considered. With the goal of having a proposed theoretical circuit that can measure current impulses with a peak of 100A, some methods have been excluded and some have been put into the system. Exclusion of some methods are because there was not enough time to dig into a completely new approach for all the methods, and therefore some methods were studied more deeply than others. The project started with a lot of reading to get understanding of the fundamental process of long air gap discharges and continued with putting the theory into a simulated system for measuring current. The proposed system has been simulated and a result has been drawn from this by looking into the bandwidth, the sensitivity and accuracy of the system.
