The topography of the power system network keeps on changing as the economy of a nation grows and it's power consumption increases. If relays must discriminate adequately between tolerable overload condition and fault condition, the power utility company must carry out a thorough short circuit study of the system periodically so as to ensure an effective relaying and switching system. A computer software, POSCODAM (Power Systems Computing and Data Management), is applied to determine the contingency fault levels in the Electric Power Grid Network of Botswana. The application of the computer software enables the load flow and the contingency levels to be determined directly, using current data from the grid system without resorting to reduction of the network The results could be of use to the engineers of the Electric Power Utility Company of Botswana
