- PublicationAn investigation into the electrical and thermal aging(2025-06-05)Aeni Haryati HashimThe fundamental aim of this project is to investigate the effect of thermal and electrical aging on the properties of the transformer oil and then suggest methods to detect the level of aging. This report discusses the possible alternative methods; they are measurements of de conductivity, ac conductivity, density, refractive index, viscosity, and visible spectroscopy of the oil. A comprehensive description on how each of the alternative method can be implemented and the results acquired is presented. Two types of samples, the capped samples and the PTFE samples are prepared in the lab to investigate the effect of thermal aging and a sample called electrical sample for electrical aging. A comparison is then made between the prepared samples and a sample from an 'in-service transformer' known as the turret sample to verify the results obtained. A series of discussion done in this report leads to a conclusion that thermal and electrical aging changes the properties of the transformer oil and the rate of aging is affected by the amount of oxygen present during the process. Also, all the methods recommended can be used to observe the property change provided the samples being compared are from the same batch. However, the density measurement will provide the best accuracy and reproducibility, as it is less prone to random errors.
18 10 - PublicationA study of the dual fuel system using LPG for a single-cylinder, stationary diesel engine(2025-06-05)Ban Kean NamA significant number of portable generators used in the Malaysia's night markets are powered by single-cylinder diesel engines. The emission from these generators causes air quality in the crowded surrounding to deteriorate. Since LPG is easily available and is commonly used as cooking gas in the night market, an experiment was carried out to study the feasibility of using LPG as alternative fuel. This dissertation discusses the results of the initial phase to convert the stationary diesel engine to dual fuel system. In the experiment, a comparative study was carried out to compare the engine performance and emission with diesel and LPG as fuel. Engine modifications were kept to minimum in order to reduce cost. The results obtained show that the engine running on dual fuel system delivered a higher power and torque than diesel fuel on high load condition. The highest power achieved by dual fuel system was 2.8kW, an increase of 10 percent output, whereas for the low load operation, the diesel fuel performed better. A cleaner emission was observed while it runs on dual fuel system. There was less NO, and CO2 emission, a reduction of 12% and 6% respectively for high load condition as compared to diesel fuel. However, a higher CO emission was recorded in the exhaust for dual fuel system, the reasons were discussed in chapter five in this dissertation.
2 11 - PublicationSolar powered remote auto feeding with GSM mobile phone(2025-03-24)Syahrunizam Mohd SoidThese thesis objectives are to build a prototype for economical and low maintenance automatic fish feeder by using solar panel and Global System Mobile (GSM) network controlled by Microcontroller Unit (MCU). The automatic fish feeder is designed to give a food by farmer wished for every day. In this project, 10W solar panel is used for supplying Direct Current (DC) voltage to charge two's 12volts batteries. The charger controller connected between solar panel and the batteries; charger controller is acted as on/off switch, it's off when then batteries are full and on when the batteries are low from desired voltage set. In this system, one of the batteries is to give supply to motor (blower) and another one is to give a supply to GSM mobile and others utilities.
103 120 - PublicationStudy on the effect of HANO sized MGO addition on mechanical strength of BI-2223 superconductor(2025-03-24)Rashpaljit Singh A/L Santokh SinghThis thesis reviews MgO particles were brought into (Bi,Pb)2Sr2Ca2Cu3O10 powder in nanosized weight portions. Mass examples were produced using the Bi2223/MgO powder and warmth treated at different temperatures. The stage arrangement and the microstructure were examined for with expansion of MgO and together with the mechanical quality. It was found that, beneath 845C, the proportion of Bi2223 stage diminished when the measure of MgO expanded. The nearness of MgO affected the microstructure of the specimens and diminished the mean size of Bi2223 grains yet at the same time have better superconducting properties as unadulterated Bi-2223. The impacts of the MgO option on the portray nanosized MgO added to superconductor utilizing x- beam diffraction (XRD) and filtering electron microscope (SEM).
15 104 - PublicationEnergy harvesting floor using piezoelectric devices(2025-03-24)Mohd Farid RamliPiezoelectric materials have a special characteristic that can produce energy that needed to operate most electric or electronic components. The piezoelectric materials will produce the energy when it captures the ambient of vibration or motion. With this special characteristic of piezoelectric materials, development of piezoelectric devices to harvest the energy has been talked since years ago. The idea of energy harvesting come from the human motion or can be classified as mechanical force. This mechanical force will be used by piezoelectric materials as their input and convert it to the electrical energy as their output. Recent study show this power generation from piezoelectric materials can be harvested and stored into energy storage. The basic of the piezoelectric device used the piezoelectric materials. A prototype of a pavement was designed to harvest the energy that produced by piezoelectric device. This piezoelectric device was placed under the pavement. As human walked on the pavement, the energy was produced and this energy was stored into energy storage. Most likely energy storage for energy harvesting will be store into Nickel Metal Hydride rechargeable battery.
