    Abstract: This study presents the analysis of various aspects of power transmission constraints associated with the Nigerian grid. The different types of short circuit faults were also simulated into the network using the Power World Simulator (PWS), to examine their effects on the bus voltages and currents. The study revealed that the Nigeria power transmission network is characterised by forced and emergency outages leading to very low power reliability and efficiency. This phenomenon have adversely affected the economic growth in the country and also caused great disruption in the lives of the citizens. Recommendations to reduce these constraints are proffered in this study to ensure good power quality and security in the network.
