|Pre-requisites//Exposure||Basic Electrical and Electronics Engineering|
- To know the necessity of different measuring instruments and their design principle
- To understand the working principle of different measuring instruments and technical solutions to handle different errors.
- To learn the architecture and working principle of advanced measuring instrument and their applications.
On completion of this course, the students will be able to:
- learn units, dimensions, standards and errors and basics of different types of measuring instruments to measure different electrical quantities
- apply their knowledge to measure electrical quantities using standard analog anddigital measuring instruments.
- measure different electrical parameters using conventional bridges and acquire data through digital measuring instruments and interpret the data.
This course deals with the basics of Electrical and Electronic measuring instruments used in laboratory and industry. In the process they learn different type of instruments like PMMC, Moving Iron, Electrodynamometer which includes voltmeter, ammeter, wattmeter, energy meter, power factor meter, frequency meter, Q meter, etc. Students will also learn about different AC and DC bridges to obtain various electrical parameters. Display devices which include DVM, CRO, DSO etc are also learnt to analyse electrical signals in the course.
After learning this subject students will be master in working principle and application of all types of measuring instruments.
