Inductance of Single Phase Two Wire Line: Inductance of Single Phase Two Wire Line - Consider a simple Two Wire Line composed of solid round conductors carrying currents I1 and I2 as shown in Fig.…
Flux Linkages of an Isolated Current Carrying Conductor: Transmission lines are composed of parallel conductors which, for all practical purposes, can be considered as infinitely long. Let us first develop expressions for flux linkages of…
Definition of Inductance of Transmission Line: The formula for definition of inductance of transmission line is as follows: Voltage induced in a circuit is given by where ψ represents the flux linkages of the circuit…
Problems of Power Sector in India: The electricity requirements of power sector in India have grown tremendously and the demand has been running ahead of supply. Electricity generation and transmission processes in India are very…
Uses of Computer and Microprocessor: Uses of Computer and Microprocessor - The first methods for solving various power system problems were AC and DC network analyzers developed in early 1930s. AC analyzers were used for…
What is Power System Engineering?: The Power System Engineering of the first decade of the twenty-first century has to face a variety of challenging tasks, which he can meet only by keeping abreast of the…
Electric and Magnetic Fields from Overhead Lines: Biological effects of Electric and Magnetic Fields from Overhead Lines and even cables in close proximity of buildings have recently attracted attention and have also caused some concern.…
Vector Control of Induction Motor: The sole idea behind the vector control of induction motor is to have an electrical drive which must offer superior performance than widely used separately excited dc motor in industry.…
Types of Forced Commutation: It was observed from the discussion on choppers and inverters that in thyristor systems fed from dc supply, the forward current does not pass through zero naturally and must therefore be…
What is Sinusoidal Pulse Width Modulation?: In Sinusoidal Pulse Width Modulation the pulse-width instead of being uniform as in the waveform of Fig. 11.55 is a sinusoidal function of its angular position with respect to…
