SWINBURNE’S TEST
This document describes how to conduct Swinburne's test on a DC shunt motor to determine its losses and efficiency at different loads. The test involves running the motor at no load to measure no load current and voltage. These values along with the armature resistance are used to calculate copper and constant losses. The efficiency is then calculated at full, half, quarter loads by determining input, output, and total losses. A MATLAB program is provided to verify the manual calculations. The results show good agreement between theoretical and simulated efficiencies.
POWER QUALITY IMPROVEMENT USING MULTILEVEL INVETERS
This document discusses using multilevel inverters to improve power quality. Multilevel inverters can generate nearly sinusoidal voltage waveforms using multiple DC sources. They allow higher voltage outputs while reducing harmonic distortion compared to traditional two-level inverters. The document outlines different multilevel inverter topologies and modulation techniques to reduce total harmonic distortion in the output voltage waveform. Applications of multilevel inverters include adjustable speed drives, electric vehicles, and distributed power generation where their ability to produce high quality power with lower harmonic distortion is beneficial.
CIRCLE DIAGRAM ON 1-PHASE INDUCTION MOTOR
1) The document describes procedures for conducting no-load, blocked rotor, and load tests on a single-phase induction motor to generate a circle diagram. Readings are taken of voltage, current, power, speed, and torque at different test conditions.
2) Calculations are shown to determine values like slip, efficiency, power factor from the circle diagram. However, the conclusion states that the efficiency calculated from the circle diagram does not match that calculated from the load test.
3) It is concluded that circle diagrams are not typically used for single-phase induction motors because the torque values differ between the diagram and actual load testing.
Automatic street light controller
This document describes an automatic street light controller circuit using an LDR (light dependent resistor) and 555 timer IC. The circuit works by using an LDR to sense light levels - when it gets dark, the LDR's resistance increases and triggers the 555 timer to turn on an LED, representing a street light. During the day when light falls on the LDR, its resistance decreases and the LED turns off. The circuit provides automatic light control without manual operation and can be used for applications like street lights that need to turn on at night.
Fuse characteristics
The document describes an experiment conducted to determine the time-current characteristics of fuse wires with different ampere ratings (5A, 10A, 15A). The experiment involved measuring the time taken for fuses to melt when subjected to increasing current levels. Graphs of time versus current were plotted for each fuse rating, showing that fuses with higher ratings took less time to melt at a given current. The graphs exhibited an inverse relationship between time and current.
Object counter
This document describes the design and working of an object counter circuit. The circuit uses an LDR sensor, op-amp, 4510 BCD counter, and 7447 seven segment decoder to count objects passing in front of the LDR. It provides the components, block diagram, circuit diagram, working principle, applications, and cost estimation of the object counter circuit. The circuit is designed to count objects in applications like manufacturing assembly lines, restaurants, banks, and airports.
Field test
This document describes a field test conducted on a DC series motor to determine its efficiency. The test involves coupling two similar 3 kW, 220 V DC series motors together, with one operating as a motor driving the other as a generator. Voltage, current and speed measurements are taken under load. Calculations are shown to find losses, efficiency of the motor (73.43%) and generator (71.77%). A MATLAB program is provided that replicates the manual calculations. The results verify the efficiency values determined from the field test.
Separation of losses in a dc shunt motor
This 3-page document describes an experiment to separate the different losses in a DC shunt motor, including friction, windage, hysteresis, and eddy current losses. It provides an introduction to the theoretical background, outlines the experimental procedure and apparatus used, includes sample data collection in a table, shows calculations to determine the individual loss coefficients, and lists the conclusions. The goal is to measure the losses at different motor speeds and excitations in order to calculate the separate contributions of each loss type based on their speed and field current dependencies.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
