Have you ever seen a ring around the Surge Arrester or other EHV equipment? What is the purpose of the Ring around the Extra High Voltage (EHV) equipment? What is the use
In power system analysis, per unit (pu) system is used to express a physical variable as a fraction of base or reference value. Per Unit (pu) is commonly used for
Symmetrical Components: Any unbalanced three phase system of currents, voltages or other sinusoidal quantities can be resolved in to three balanced of phasors which are known as symmetrical components of
First electric power system was build in New York city in 1882. DC power was generated by steam generator supplying power to 59 consumers. During the decade many small power systems
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 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
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
Harmonics in the power system are generated due to the usage of non linear load. Some of the effects of harmonics on the performance of induction machine are: Core losses in
Most of the faults on over head lines are transient in nature. About 85% to 90% of faults are momentary and caused by tree branches, lightning, birds etc. These conditions
A current limiting reactors is also called as series reactors. It is an inductive coil having large inductive reactance compared to the resistance and is used to limit the short
