Commutation failures are very frequent dynamic events in high voltage dc (HVDC) transmission systems. Commutation failure is mostly observed at the inverter side of HVDC links, where large firing angles are used. The minimum value of the extinction angle required for the proper operation of a valve is specified by the valve manufacturer; however,... Continue Reading

A traffic light also known as a traffic signal,  stop light and go light, robot or semaphore is a signally device positioned at four (cross) junction, pedestrian crossing or other locations in other to indicate when it is safe to drive or walk using a universal color code ( and in precise sequence for those that are color blind). Traffic... Continue Reading

The present invention relates to an improved control system for starting a three phase induction motor comprises improved power contactors configured to have a pair of three pole delta and main contactors, and a single pole star contactor for supplying AC power to star position and delta position, a timer for controlling AC power supply...

An induction or asynchronous motor is a type of AC motor where power is supplied to the rotor by means of electromagnetic induction, rather than by slip rings and commutators as in slip-ring AC motors. Single phase induction motor is the most familiar of all electric motors & they are similar to a 3-phase squirrel cage induction motor. It... Continue Reading

The energy sector plays a major role in driving Kenya’s economy. The need to conceive, develop and sustain energy generating sources cannot be underestimated.   Being a growing economy, Kenya therefore needs to redirect her effort in production of self-sustaining energy generating sources. It is in this line that the government through the... Continue Reading

   Abstract The project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY  CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones,  bombs, and other metallic objects that are hidden from view. The design is based on the principle  of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is... Continue Reading

This project deals with the design and development of restaurant order meal system, in order to reduce the number of staff. In meal ordering project, you can request for any kind of food or drinks available in the restaurant which contains the menu embedded in each button. Microcontroller is the central processing unit CPU of this project... Continue Reading

The aim of the project is to design a renewable energy system that can meet the current and  projected electricity demands for the island of Great Cumbrae. This should be achieved by  providing a stable electricity output and the meet the calculated total annual base load supply of  11.29 GWh. In addition to providing a stable supply of...

In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of... Continue Reading

Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone...

Whenever we think of redefined security, we think of coded electrical door lock. It is a microcontroller based security door lock that can be used in homes, offices, laboratories, etc. for more reliable and high fidelity door control system, powered by electrons panel or electromechanical panels. Due to high rate of insecurity, especially... Continue Reading

                       Abstract This temperature control fan can be controlled using a microcontroller when it detects a certain temperature that has been set. The purpose of this project is to prevent the waste of voltage usage when it is not hot enough for fan to be needed. The temperature control fan has three different speeds. Each... Continue Reading

Research and optimization of cooling of electronic components using heat sinks becomes increasingly important in modern industry. Numerical methods with experimental real world verification are the main tools to evaluate efficiency of heat sinks or heat sink systems. In this research, the physical problems associated with heat removal of... Continue Reading

The aim of this project, the design and implementation of an RF communication link, is to design a communication link between a source and a destination and study the properties of the signal being generated by the source (generator).
