Abstract

The paper studies the problem of the impact of basic circuit and mode parameters of the equipment and shop-floor grids on the value of the equivalent resistance of low voltage grids of the industrial enterprises. The conditions, under which non-accounting of contact joints resistances of switching devices does result in the substantial error in the process of determination of the equivalent resistance in 0.4 kV grid, are considered.
