BEE405 ELECTRICAL AND ELECTRONIC MEASUREMENTS

OBJECTIVE: The study of the course will help the students to apply all types of common electrical and electronic instruments with the knowledge of their construction and working.

1.MEASUREMENT OF VOLTAGE AND CURRENT


Classification - measurement of voltage and current - permanent magnet moving coil and moving iron meters - dynamometer type meters - measurement of inductance and capacitance using bridges

2.MEASUREMENT OF POWER AND ENERGY


Dynamometer type wattmeters, Induction type energy meters - single phase and poly-phase, testing and calibration of energy meters power factor meters - synchroscopes.


3.MAGNETIC MEASUREMENTS


Ballistic galvanometers and flux meters, B.H curve and permeability measurements - iron loss measurements by magnetic squares and C.R.O.

4. INSTRUMENT TRANSFORMERS


Theory - ratio and phase errors of current and potential transformers – capacitor voltage transformers -use of instrument transformers with wattmeters.

5.SPECIAL INSTRUMENTS


KVAh and KVARh meters - Maximum demand indicators - meggar- laboratory measuring instruments- Standard signal generators and function generators ,TVM and frequency meter, distortion factor meters and phase meters.
