Three Phase Cycloconverter - Types, Working and Applications: A cycloconverter converts ac at one frequency to an ac of another frequency. Cycloconverters can be classified as single-phase to single-phase, three-phase to single-phase and three-phase to…
Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter as shown in Fig. 7.1. Only the current I flowing through the…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be assumed that by the time…
Performance of CMOS Gates: The Performance of CMOS Gates which based on following different categories namely, Operating Speed : Slower than TTL series. Approximately 25 to 100 ns depending on the subfamily of CMOS Inverter…
Simpson Theory of Lightning: The factors that contribute to the formation or accumulation of charge in the clouds are too many and uncertain. But during thunderstorms, positive and negative charges become separated by the heavy…
Methods of Exciting Waveguides: In order to launch a particular mode in a Methods of Exciting Waveguides, some arrangement or combination of one of more antennas is generally used. However, it is also possible to…
Horn Antenna Design: Horn Antenna Design - As we know, a waveguide is capable of radiating energy into open space if it is suitably excited at one end and open at the other. This radiation…
Breakdown in Liquid Dielectrics: Liquid are used in high voltage equipment to serve the dual purpose of insulation and heat condition. They have the advantage that a puncture path is self-healing. Temporary failures due to…
Schottky Barrier Diode: Schottky junctions have been shown and described throughout this chapter, in conjunction with various devices that use them in their construction in Figure 12-4. Accordingly it will be realized that the Schottky…
Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by the source itself. This is…
