Methods for Calculating Expected Voltage Drops of Prospective Power Transmission Systems

This paper provides a description of the options for calculating the electrical parameters of power transmission systems in the cases of both one and two parallel consumers. The meaning of the root formulas of the quadratic equations is analyzed and the variants of how to determine the correct root in relation to the real situations is studied, concluding that the second root is also possible from the point of view of mathematics and electrical engineering. The significance of discriminant expressions is analyzed by numerically studying cases with electric transport and its catenary by performing simulations.
