Power measurement is a valid technique to measure that how much the power is being transmitted through the entire system.
In this presentation you will estimate and understand the following objectives
Wattmeter as a device
Power measurement techniques
Classical based history
Construction of wattmeter
Working of Wattmeter
Power measurement of direct and indirect way
Power measurement in three phase applications
Applications of Wattmeter
Speed control in 3 phase induction motorKakul Gupta
Speed control in induction motors is required for efficient operation
Various methods of speed control through semiconductor devices:
1. Stator voltage control
2. Stator frequency control
3. Stator voltage control
4. Stator current control
5. Static Rotor Resistance Control
6. Slip Energy Recovery Control
Rectifier and amplifier type of instruments are used and studies in the filed of instrumentation and Measurements as they provide authentic source to explore more ideas about the types and construction of such instruments
This presentation gives you brief information about the basics of magnetism and all definitions related to Magnetism like Magnetic flux density, Magnetic field strength, Permeability, Magnets, Types of the magnet, Reluctance, etc.

2. INTRODUCCIÓ L’electricitat és una de les formes d’energia més utilitzades per l’ésser humà. L’emprem pràcticament per a tot, actualment seria impossible viure sense l’electricitat. Gràcies a l’electricitat podem il·luminar ca nostra, fer funcionar els nostres electrodomèstics, màquines ... L’èxit de l’electricitat com a font d’energia es troba en la facilitat per a obtenir-la, transportar-la i transformar-la en altres energies.
