Development of the Physical Model of a Rural 0.4 kV Electrical Network

The physical model of a rural 0.4 kV electric network containing a transmission line sectioning device and a photovoltaic array is presented. The basic electric circuit of the model and its operating principles are given. The model parameters are substantiated taking into account the similarity theory. The reliability of the 0.4 kV rural electric network model is assessed using the example of modeling single-phase short-circuit currents and comparing them with the GOST 28249-93 values.
