The IT-program SIMNET serves the calculation of currents and voltages in a network with wires running in parallel, which is typical of a railway line with contact wire, catenary wire, supply wire, feeder, earth wires, lines and cables.
SIMNET carries out a network calculation from a model, built up of chains of cells of definable length, which consist of parallel wires, connections between the wires and connections to earth. On the basis of the input data, SIMNET calculates the self-inductance and the capacitance per unit length of the individual wires, the inductive and capacitive coupling of all the wires to each other and to earth. The skin effect in the wires, the earth current depth and the earth resistance are all taken into consideration.
The program is especially useful for
