Electrical power must be delivered to consumers in a safe, efficient, economical and reliable way. This makes it necessary to have power systems which will guarantee all these requirements. Currently the Tanzania electric supply company (TANESCO) lacks a proper method of fault location in the distribution level and more so in the underground lines. The company has a limited length of underground and marine power lines but plans to employ underground power lines in distribution level especially in urban areas and a major product is on-going at Ilala area in Dar-Es-Salaam. Fault detection and location is most difficult in underground lines. This project was aimed at designing an accurate, cost effective and on-line fault detection and location system for underground distribution power cable. This was achieved through reviewing the available literature on fault location techniques to reveal drawbacks, gathering useful information from TANESCO and application of Electrical Engineering skills grasped during the four years of study. Numerical and descriptive data obtained from TANESCO were analyzed and used in designing a system that meets the specified technical requirements. Programming and simulation software known as Atmel studio 7 and proteus were used during design and simulation. Finally physical prototype was assembled and tested.

Impacts on gross domestic product (GDP) and social status of the region were examined through basic information supplied by, mainly, industrial technicians, domestic power consumers and The Tanzania electric supply company (TANESCO). The methods used in data collection were direct interview, questionnaire and literature reference. Questionnaire was interviewer-guided while references were obtained from concerned authorities. The total power demand of the region is currently 45 MW of which 15.5 MW serve industrial consumers within Mwanza city. The remaining power serves domestic consumers in the city and other parts of the region. Doubling the total power demand implies increasing the current level to about 90 MW. Economic impacts were found to be improvement in industrial sector and life standards. Mwanza region contributes about 7% of the national GDP from the agricultural, mining and industrial activities within the region. Doubling available power would boost both regional and national GDP but it should be noted that ensuring power reliability is the primary step towards improving the income from power consumption. On the other hand, social status would be improved in terms of individual life standards, communication and entertainment, education quality and health services. Finally, it was found that if the current power demand and supply scenario is left static, it would be a great let down it terms of reduced regional per capita income (PCI) and deteriorated social status. We recommend that the vision 2025’s sections concerning energy and power be implemented as planned so as to realize any significant economic and social expectations.

Electrical machines; Transformers, motors and generators are essential at any level of electrical power generation, transmission, distribution or utilization. These experiments were intended to enhance our knowledge on electrical machines and drives.
