To allow for optimum operation of the secondary system of lines, it is essential that the performance of the system be evaluated. Optimal functioning refers to the most desirable and favorable system of operation such as: improved system reliability, adequate and satisfactory electric potential profile, no imbalances in the phases of electric potential and electric charge, complete absence of overloading of electrical conductor used and energy converting devices and approved and allowable loss. This investigative research assesses the efficiency of the distribution system of lines resulting from electric potential deviation, electric potential imbalances, electric potential losses and electric potential fluctuation through the use of MATLAB/Powerlib tools. This research offers most desirable and favourable assessment of Typical, Sub-Saharan Africa secondary unbalanced system of lines. The system of lines was designed with approved and accepted system of line parameters for secondary Sub-Saharan Africa typical system of lines through the use of MATLAB/Powerlib software. The desire outcome got from the MATLAB model with the 500 meters distance for unbalanced system of lines is within permitted actual electric potential limit of minus five per cent for electric potential loss, plus and minus five per cent for electric potential deviation, electric potential imbalances is less than 2 per cent, and the electric potential profile at the end users is within 0.95 and 1.05 per-unit.
