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 increasing rate of electrical fires in the Kumasi Metropolis has become a matter of worry to many residents. Residential fires in Kumasi constitute the highest incidence of fire outbreaks recorded. In an attempt to address the alarming rate of fire outbreaks in Ghana, the Fire Precaution (Premises) Regulation (2003) LI 1725 was passed to enable Ghana National Fire Service (GNFS) to carry out inspection of proposed and existing premises, review building plan with regard to�...

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 The study was designed to investigate the impacts of mining on electrical circuits in the catchment communities with specific reference to Damperyaw mining company. A careful observation of the activities of Damperyaw mining community at the catchment areas in terms of effects of the prevailing environmental conditions reveal that, most catchment communities have issues and concern about how the mining activities are affecting their electrical gargets and appliance. The descri...
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,...
