ABSTRACT This study focuses on the design and construction of a solar cell phone charger with battery bank. It is designed to meet up with the high demand of power supply needed to keep our cell phone batteries charged especially people in open public places like traders in Kejetia market in the Ashanti region of Ghana. A solar cell phone battery charger is an electrical device that converts the energy of sunlight directly into electricity by the photovoltaic effect. It does this by the use o...
ABSTRACT The main purpose of the study was to evaluate the perception of the consumers of electricity regarding the use of prepaid meter system in the Koforidua Municipality. This study employed quantitative and descriptive research design to collect and analyze data. The population for this study was individuals who consume electricity in the Koforidua Municipality in the Eastern Region of Ghana. The population for the study was two thousand six hundred (2600). The random (probability) sampl...
ABSTRACT Fiber backbone is almost at the verge of replacing the microwave link completely owing to the high demand for capacity. To achieve this high capacity with fiber in other to reduce complaints of poor quality of service, proper deployment techniques must be employed by network operators. This project delves into the network elements, their installations and their interconnection topologies of the various fiber backbones deployed by all the network operators in Ghana. The analyt...

The researcher used descriptive research design for the study. The study used quantitative and qualitative research approach. The total population for the study was 32 students and 5 teachers totaling 37...
ABSTRACT This research was designed to determine the comparative study of practical skills acquisition in electrical engineering training programme in Accra and Kumasi Polytechnics. The study population was made of 316 and 262 making a total of 578 students in the Department of Electrical/Electronic Engineering from the Accra and Kumasi institutions respectively. A samples size of 25% was randomly selected from the total populations of the two study institutions. A total number of 145�...
ABSTRACT The main aim of any electric power supply system in the world is to provide uninterrupted power supply to all its consumers at all times. But in developing countries like Ghana, the electric power generated does not meet the demands of the growing number of consumers of electricity hence there is inadequate power supply which results from frequent power outages. This does not promote development in the public and private business sectors it has left many people without electricity. ...
ABSTRACT The main objective of this project is to develop a simple low cost microcontroller based remote distribution transformer monitoring system using wireless technology which acquires key transformer parameters like temperature, voltage and load current using various sensors to display the real-time values on LCD and forwards them to a cell phone in a remote location by SMS. This project was developed by using Arduino board with ATMEGA328 Microcontroller, SIM 900 GSM Module, LCD d...
ABSTRACT The main objective for this study was to assess the challenges associated with the use of photovoltaic modules in Ahanta West District of Ghana. Survey was considered to be the best for the research design. Data were gathered by means of issuing questionnaires to some selected groups who one way or the other use solar power in the research district. In all, 68 respondents were purposively selected from some households, schools, clinics, companies and traders who use or deal with th...
ABSTRACT The physiological monitoring device is use to detect patient vital signs during treatment. It measures the rate a person that performs routine activities. The device detects body posture and activities that are of significant interest in applications such as sports, medicine, and military training. The study uses design of wireless controlled physiological monitoring device using ATMEL microcontroller. The physiotherapy is performed by a designed robotic arm fixed to the patie...
ABSTRACT Typical switched-mode power supplies employ diode rectifiers for the AC to DC conversion. They draw input current in short pulses rather than in smooth sine waves and this puts stress on the wiring, circuit breakers and even distribution equipment provided by utilities. This type of utility interface generates harmonics and both of the input power factor (PF) and total harmonic distortion (THD) are poor. To minimize the stresses and maximize the power handling capabilities, active ...
ABSTRACT Technological intervention is seen as any electronic item or equipment or application that is used to increase or maintain and or improve daily living work/productivity capabilities of children/students. The study assessed the impact of the “Better Ghana agenda laptops” on teaching and learning in basic schools in the Wenchi municipality, the challenges in the implementation of the policy and to find out the criteria used for the distribution of the laptops. Specifically, 100 st...
ABSTRACT Grid-connected solar PV systems, though the fastest growing renewable energy technology in the world, have not been fully exploited in Africa, one of the reasons being the very high initial investment. Prices of solar PV systems have however been on a decline for the past few years due to technological innovations which have led to improvement in cell efficiencies and the economies of scale resulting from increase in production. The main purpose of this thesis is to perform,...
