In this article, we present a repeatable and calibrated arc generator and the method we developed to initiate an arc. The test bench we propose can generate AC and DC currents and series and parallel arc faults on variable loads. Using a step up transformer, arc initiation is obtained by producing an overvoltage: the arc is then sustained using an AC or DC line generator. Atmospheric conditions (temperature,...
Arc faults can be accidentally produced in any electrical system. In order to test arc detection systems (AFCB), but also to design electrical systems, it is possible to simulate arcs faults starting from models. To analyse and detect these arc faults, accurate models are needed. In this paper a new approach to the arc modelling is discussed. In the first part of the paper we compare the different...
This article describes the design and use of a repeatable and calibrated arc fault generator. We have developed a test bench which can generate AC and DC currents and series and parallel arc faults on variable loads and have chosen a method which consists in producing an overvoltage in arc initiation, obtained with a step-up transformer; a line generator (AC or DC) then sustains the arc. We show the...
