EEC 348 ELECTRICAL TRANSMISSION AND DISTRIBUTION Tutorial 2026

About this paper

EEC 348: A tutorial sheet for EEC348 Electrical Transmission and Distribution, Department of Electrical and Electronic Engineering, University of Buea College of Technology, containing 11 exercises. Exercises 1-3 duplicate the EEC348 CA exam (catalogued separately); the three new problems fully transcribed and solved here cover: GMD/GMR analysis of an unbalanced single-phase circuit with composite go/return conductors to find total loop inductance; the percentage change in per-phase inductance and capacitance when a three-phase line is upgraded from a single ACSR conductor per phase to a three-conductor bundle with wider phase spacing; and a full short-line analysis (source voltage, voltage regulation, transmitted power, and transmission efficiency) of a 16 km, 69 kV three-phase line under two different receiving-end load conditions. Exercises 7-11 (ABCD-constant determination, a rigorous nominal-pi calculation, a multi-part power-loss case study, a voltage-drop network calculation, and an open-ended network-design report) were omitted for scope.
