DESIGN AND CONSTRUCTION OF A 60AMP THREE PHASE AUTOMATIC CHANGE OVER SWITCH.

ABSTRACTThe design and construction of a 60A, 3-Ф automatic power changeover from public utility supply to generator and vice versa was aimed at providing a useful system for use in our homes or offices. The system was achieved with a 66A 3-Ф contactor, 100mA transformers and relays. The system turns on a generator when the public utility (PHCN) is off by cranking the starter and a provision was made to stop cranking when the generator is fully started. A delay was provided to stop the gene...

REPAIR AND REHABILITATION OF A WINDOW UNIT AIRCONDITIONER

ABSTRACT The project work Rehabilitation and Repair of A Window Unit Air Conditioner exposes us to the internal working mechanism of the window unit a.c.  The working principles component unit, faults and effective repairs carried out to ensure the serviceability of the broken down unit. It buttress the need for routine maintenance, and effective repair works to be carried out on the a.c unit as well as other electrical gadget to ensure long service life and efficiency of the require...

DESIGN AND INSTALLATION OF 200 WATT SOLAR POWER SYSTEM

ABSTRACTThe 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective gadgets like cut out switches; to give the 200W expected. The solar panel was mounted outside the building to allow for maximum collection of sun ene...

DESIGN AND CONSTRUCTION OF 20WATTS WIRELESS PUBLIC ADDRESS SYSTEM

ABSTRACTIt has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM” is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sound...

DESIGN AND FABRICATION OF WHEEL AND BRAKE SYSTEM OF A TIPPING TRUCK

ABSTRACTThe purpose of this research work is to design, fabricate and install a hydraulic brake system on a wheel system of an agricultural tipping truck. For an efficient functioning of the brake system some measures have to be strictly considered; the weight of the vehicle and the external load.The engineering materials used in the fabrication of the wheels system include metals, ceramics and polymerics.Despite the efficiency of the brake there must be routine checks and maintenance to ensu...

DESIGN AND CONSTRUCTION OF AN INVERTER TYPE ARC WELDING MACHINE

AbstractWelding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint. Because of its strength, welding is used to join beams when constructing buildings, bridges and other structures. Weld...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...

DESIGN AND CONSTRUCTION OF AN AUTOMATIC VOLTAGE STABILIZER

ABSTRACT In the world today, the use of power supply in electronics equipment and gadgets has increased and it is still increasing.  These power supplies are not stable as required by these electronics. This arise the need for the power stabilization as to overcome this problem  This project handles this problem very well.  Some recommendations were also made on this topic and student and users of electronics equipment will find them useful.TABLE OF CONTENTSCover PageTitle ...

DESIGN AND CONTRUCTION OF AUTOMATIC PHASE SELECTOR

AbstractAs the growing population of human race widens the gulf between energy supply and energy demand, the imbalance in energy availability sent researchers into excavating for a way of settling this age long squabble. A lasting solution is vested on alternative use of the renewable energy source, a project that is yet to be widely applied. Hence, the continuation of the unsettled yearns for sufficient power. Consequently, the power lines are frequently over loaded resulting to a trip of po...

PATIENT HEARTBEAT AND TEMPERATURE MONITOR

AbstractHeart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm). The human heart pounds to pump oxygen rich blood to the muscles and carry cell waste products away from the tissues. Heartbeat rate can vary according to the demand of the muscles to absorb oxygen and excrete carbon dioxide changes such as during exercise or sleep. It also varies significantly between individuals based on age, fitness and genetics. This means that the heart must ...

HOME CONTROL SWITCH AUTOMATION USING GSM COMMUNICATION

ABSTRACTThe advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when ...

FORMULATION AND PRODUCTION OF ALCOHOL FROM PALM WINE.

ABSTRACTThis research work was arrived as the formulation and production of ethanol (ethyl alcohol) from the fermentation of palm wine. A fresh palm wine was ated which was obtained  from Emene in Enugu State.  The characteristics that was tested before and after fermentation were; specific gravity, refractive index and PH value of the fermentated palm wine was first determined, after which samples were formulated for fermentation.  The yeast that was used in the course of ferm...

CONSTRUCTION OF MICROCONTROLLER BASED VEHICLE SPEED ALARM.

ABSTRACT The project is based on Construction of microcontroller vehicle speed alarm system which automatically warns the driver by activating a panic alarm which is triggered on when the driver exceeds the speed limit set in the system which also stops the alarm when the speed is reduced below the set speed limit. A speedometer system is used to monitor the speed of the car. The voltage output of the speedometer system is used to set the time the alarm comes on. The other component part...
