Short Circuit Calculation Program

The Short Circuit Calculation program calculates short-circuit protection requirements for mine trailing cables and motor cables. The program takes into consideration electrical parameters of the power supply (i.e., capacity, impedances, system voltage, etc.), as well as the power distribution system (i.e., cable ampacity and length, insulation temperature ratings, transformer values, etc.). In addition, this latest version calculates loads and checks them against cable ampacities, in addition to the short-circuit calculations.
