Development and Experimental Validation of Scaled-Down Analogous Power Distribution System with Single-Phase Arc Fault Generator

Existing arc generator is usually integrated with a simplified systematic Thevenin equivalent circuit to study the dynamic arc behavior. It cannot be used for the arc fault detection and location research in the neutral non-effectively grounded distribution system (NGDS) because the interaction between the arc fault and the distribution system is ignored. In this paper, one arc generator with additional fault condition control module is proposed, discussed and realized. At the meantime, one scaled-down NGDS is also realized to integrate with our proposed arc generator. The accomplished devices are detailed illustrated and discussed. The effectiveness of the proposed testing platform integrated with the analogous distribution system and the arc fault generator have been validated by the recorded voltage and current waveforms in the experiments.
