Torque Tube Level Measurement Principle
The displacer type liquid level measuring instrument is not a float as such, for the displacer is heavier than the  process fluid and the displacer moves very little during changes in…
Difference between Induction motor and Synchronous motor
Induction Motor: 3 phase induction motor is self starting. Self starting torque is generated hence no special means is required for starting of Induction motor. It is to be remembered…
Advantages & Disadvantages Induction Motor
Induction Motor: Almost 70% of the machines used in industries now a days are 3 phase induction motors. It works on the principle of induction where electro-magnetic field (emf) is induced in…
Advantages & Disadvantages of AC power and DC power
First electric power system was build in New York city in 1882. DC power was generated by steam generator supplying power to 59Â consumers. During the decade many small power systems…
Rotor Angle Stability of Synchronous Generators in Power System
Rotor Angle Stability: Rotor angle stability is the ability of the interconnected synchronous machines running in the power system to remain in the state of synchronism. Two synchronous generators running…
Harmonics effect on Transformer
Harmonics distortion effect on Power System and their impact on Induction Motors are already discussed. Some of the disadvantages of harmonics and their impact on the transformers are: RMS current increase Eddy Current loss increases DC offset…
Why Reactive Power is Generated at Load
Reactive Power if possible should be generated close the load centers or close to the point of its consumption. Some of the reasons why reactive power cannot be transmitted to long distances…
