Turbocompressors: The turbocompressors and blowers in the industry require drives rated up to 40 MW. Drives of large rating are also required in steel industry blast furnace blowers in natural gas pipelines and liquefaction processes…
Basic JFET Biasing Circuits Comparison: The Basic JFET Biasing Circuits Comparison (gate bias, self-bias, and voltage divider bias) are similar in performance to the three basic BLIP bias circuits, (base bias, collector-to-base bias, and voltage…
Basic Requirements of Protection System: Protection system is an extremely important part of the power system as it is provided to operate under abnormal conditions to prevent failure or isolate trouble and limit its effect.…
Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound for three phases and identical…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading but they contribute to the…
Impedance Matching using Half Sections: While connecting number of different sections in the filter, it is very important to match the impedances of the sections at the junction points. Thus a T section should not…
Decentralized Control System Definition and Techniques: Decentralized Control System - In view of the large size of a modern power system, it is virtually impossible to implement either the classical or the modern LFC algorithm…
Frequency Domain Analysis: Frequency Domain Analysis - As we now already, the responses of the networks to the various time dependent inputs such as step, ramp, exponential etc. are studied. Let us now discuss the…
Delta to Star Conversion and Star to Delta Conversion: In the complicated networks involving large number of elements, Delta to Star and Star to Delta Conversion considerably reduce the complexity of the network and network…
DC Traction using Semiconductor Chopper Controlled DC Motors: Chopper control has replaced resistance control in all dc traction schemes, such as 1500 V dc main line and suburban traction, 750 V dc underground traction and…
