JNTUH B.Tech 3rd year (3-2) Electrical and Electronics Instrumentation gives you detail information of Electrical and Electronics Instrumentation R13 syllabus It will be help full to understand you complete curriculum of the year.
Objective
Electrical measurements course introduces the basic principles of all measuring instruments. It also deals with the measurement of RLC parameters voltage, current Power factor, power, energy and magnetic measurements.
UNIT-I
Introduction to Measuring Instruments Classification —deflecting, control and damping torques — Ammeters and Voltmeters — PMMC, moving iron type instruments — expression for the deflecting torque and control torque — Errors and compensations, extension of range using shunts and series resistance. Electrostatic Voltmeters-electrometer type and attracted disc type — Extension of range of E.S. Voltmeters.
UNIT — II
Potentiometers & Instrument Transformers Principle and operation of D.C. Crompton’s potentiometer—standardisation — Measurement of unknown resistance, current, voltage. A.C. Potentiometers: polar and coordinate types standardisation — applications. CT and PT — Ratio and phase angle errors.
UNIT —III
Measurement of Power & Energy Single phase dynamo meter watt meter, LPF and UPF, Double element and three element dynamo meter watt meter, expression for deflecting and control torques — Extension of range of watt meter using instrument transformers — Measurement of active and reactive powers in balanced and unbalanced systems. Single phase induction type energy meter — driving and braking torques — errors and compensations — testing by phantom loading using R.S.S. meter. Three phase energy meter — tri-vector meter, maximum demand meters.
