JNTUH B.Tech 4th year (4-1) Electrical Measurements Lab gives you detail information of Electrical Measurements Lab R13 syllabus It will be help full to understand you complete curriculum of the year.
The following experiments are required to be conducted as compulsory experiments
- Calibration and Testing of single phase energy Meter
- Calibration of dynamo meter power factor meter
- Crompton D.C. Potentiometer — Calibration of PMMC ammeter and PMMC voltmeter
- Kelvin’s double Bridge — Measurement of resistance — Determination of Tolerance.
- Dielectric oil testing using H.T. testing Kit
- Schering bridge & Anderson bridge.
- Measurement of 3-phase reactive power with single-phase wattmeter.
