LEARNING OUTCOMES
After studying Electrical and Electronic Instrument and Measurements (EEIM), students will able to :
• Connect and repair different indicating and recording instruments in electric circuits.
• Measure different electrical quantities like current, voltage, power, energy, power factor, frequency etc.
• Select the type and range of instruments to be used for the job.
• Operate CT (Current Transformer) and PT (Potential Transformer) for measurement.
• Select and use suitable sensors for measurements of different non-electrical quantities.
• Use instruments for measuring different electrical quantities.
• Use sensors for measuring non electrical quantities.
• Operate on smart metering system in industry.
LIST OF PRACTICALS
1.) Use of analog and digital multimeter for measurement of voltage, current (A.C/D.C) and resistance.
2.) Measurement of pressure by using LVDT.
3.) To measure the value of earth resistance using earth tester.
4.) To measure power, power factor in a single-phase circuit, using wattmeter and power factor meter and to verify results with calculations.
5.) Measurement of power and power factor of a three-phase balanced load by two wattmeter method.
6.) Measurement of voltage and frequency of a sinusoidal signal using CRO and draw wave shape of signal.
7.) Measurement of power in a 3 phase circuit using CT, PT and 3-phase wattmeter.
8.) Use of LCR meter for measuring inductance, capacitance and resistance.
9.) To record all electrical quantities from the meters installed in the institution premises.
10). To measure Energy at different Loads using Single Phase Digital Energy meter.
11.) Measurement of temperature by using thermister/Thermal Imager.
12.) Calibration of single phase and three-phase energy meter and digital energy meter.
INSTRUCTIONAL STRATEGY
After making the students familiar with measuring instruments, they should be made conceptually clear about the constructional features and make them confident in making connections of various measuring instruments. Teacher should demonstrate the application of each measuring instrument in laboratory and encourage students to use them independently.
MEANS OF ASSESSMENT
− Assignments and quiz/class tests, mid-term and end-term written tests, model/prototype making.
− Actual laboratory and practical work, model/prototype making, assembly and disassembly exercises and viva voce.
