Mine Electrical Power Systems. Transients Protection, Reliability Investigation, and Safety Testing of Mine Electrical Power Systems. Vol. IV -use of Programmable Calculators in Mine Power Systems D.
This report describes software developed for programmable calculators that is useful in the analysis and design of mine electrical power systems. The programs are equally useful for any industrial or commercial power system. All programs are written for both the hp-97 and ti-59 programmable calculators. Listings of both versions of the 12 programs that were developed appear in the report. For each program the following items are provided: a description of the program's capabilities, the solution technique used, instructions on how to use the program, a worked-out example with data and results, and listings of the programs for the hp-97 and ti-59 programmable calculators. Typical problems that can be attacked with these programs include ground bed design, selection of contactor size, fuse size, relay settings, instantaneous overcurrent trip settings for trailing cables, allowable cyclic cable loading, short circuit analyses, prediction of transient voltages, and others.
