Taut Band Instrument: The Taut Band Instrument utilizes the same principle as the D'Arsonval movable coil and fixed magnet. The primary difference between the two is the method of mounting…
Practical PMMC Movement: The basic Practical PMMC Movement (also called a D'Arsonval movement) offers the largest magnet in a given space, in the form of a horse-shoe, and is used…
Permanent Magnet Moving Coil Instrument (PMMC): In this type of Permanent Magnet Moving Coil Instrument (PMMC), we have a coil suspended in the magnetic field of a permanent magnet in…
Zero Sequence Impedance of Transmission Line: Zero Sequence Impedance of Transmission Line - A fully transposed three-phase line is completely symmetrical and therefore the per phase impedance offered by it…
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…
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…
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…
Air Gap Power in Induction Motor | Torque and Power Output Equation: Air Gap Power in Induction Motor - The circuit model is shown in Fig. 9.10. The power crossing…
