Transient analysis of 33 KV power transmission line stability of Egi community\nis considered in this research work with the aim of reducing the frequency\nof fault occurrence and voltage collapse in the network. The supply is\ntaken from Egi generating station located at Total Nigeria Limited Gas Plant\nObite at voltage level of 33 KV to Egi communities. This work focuses on the\ntransient nature of network stability since transient fault is the most dangerous\nin electrical systems. The swinging of the generator rotor in the event of\ntransient three-phase short circuit fault can be monitored by the circuit\nbreakers and the protective relays which causes mal-functioning of the circuit\nbreakers and protective relays leading to abnormal behavior of the network.\nTherefore, data obtained from the power station were used as a case study of\nIndependent Power Producer (IPP) in Nigeria. For investigation of the power\nangle, angular velocity, rotor angle differential changes, and angular velocity\ndifferential changes, an electrical transient analyzer tool was employed (ETap\nversion 16.00) for circuit breaker and protective relay time setting of (0.00,\n0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60). The work\nused the Trapezoidal numerical technique for data analysis. The graphs were\nplotted using Matlab R2015a and the results obtained showed that when a\nsymmetrical three-phase short circuit fault occur at one or any of the feeders,\nthe fault must be cleared as quick as possible through the coordination of the\ncircuit breakers and protective relays.................................
