Pre-Requisite Knowledge

Electro-Mechanical Workshop/Electronic and Measurement Lab

Summary of Content

This module covers the basic concepts of electrical measurements using analogue and digital instruments. Working principle and construction details of measuring instruments like Ammeter, Voltmeter, Wattmeter and CRO are covered in this module. Transducers and display devices are also included to understand the use of electronic instruments in measuring electrical and physical quantities. Tutorials will be used to reinforce the module material discussed during lecture sessions.Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.

Syllabus

The teaching syllabus will cover the following areas: Outline of Measurements : Methods of measurement, electrical units, construction of galvanometers, potentiometers, AC bridge methods to measure-self capacitance, Q factor and frequency etc. Measuring Instruments: Constructional details of indicating, recording and integrating type of instruments, principle of moving iron, moving coil, thermocouple type ammeter, and voltmeter, dynamometer type wattmeter, power measurement in 3-phase system, induction and electronic type energy meters, error testing. Instrument transformers: Theory of current and potential (CT and pt) transformer, determination of ratio and phase errors of CT and pt, effect of change in burden and power factor on the ratio and phase angle of CT and pt. Transducers: Classification, transducers types, RLC photocell. Basic scheme of measurement of displacement, velocity, acceleration, strain, pressure and temperature. Display devices and Oscilloscope: Concept of digital measurement, construction of Nixie tubes, LED's, LCD's discharge devices. Study of basic CRO using block diagram and various stages, high frequency CRO considerations, Sampling and storage oscilloscope.

Learning Outcomes

On completion of this module the student should be able to:1. Understand the concepts of analog instruments to measure the electrical quantities. (AM1, AM5)2. Working principle and construction details of various electrical and electronic instruments. (AM1, AM5)3. Application of measuring devices to evaluate the accurate quantity and to find out the errors.(AM1,AM5)

Teaching / Learning Strategy

The main teaching method will be based on lectures with separate module of laboratory exercises used to relate theoretical concepts to practical experience. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to Electrical and Electronic Measurement. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
