Serial Communication Interface 8251: Most of the microprocessors are designed for parallel communication. In parallel communication number of lines required to transfer data depend on the number of bits to be transferred. For example, to…
Node Elimination Technique in Power System: In stability studies, it has been indicated that the buses to be considered are those which are excited by the internal machine voltages (transient emf's) and not the load…
Network Observability and Pseudo Measurements: A minimum amount of data is necessary for State Estimation (SE) to be effective. A more analytical way of determining whether a given data is enough for SE is called…
Stator Voltage Control of Induction Motor: By reducing Stator Voltage Control of Induction Motor, speed of a high-slip induction motor can be reduced by an amount which is sufficient for the speed control of some…
Unbalanced Phase Current: The Unbalanced Phase Current in a 3-phase system can be expressed in terms of symmetrical components as under : Fig. 18.6 shows the vector representation of symmetrical components. It is usually profitable…
Important Definition of Phase Locked Loop (PLL): Some Important Definition of Phase Locked Loop PLL are as follows : Lock Range: When PLL is in lock, it can track frequency changes in the incoming signal.…
Applications of Power Transformers: Transformers are the first to encounter lightning and other high voltage surges. The transformer insulation has to withstand very high impulse voltages many times the power frequency operating voltages. The Applications…
Arc Lamp -Definition, Working Principle and Types: In an arc lamp electric current is made to flow through two electrodes in contact with each other which are drawn apart. The result is an arc being…
Antenna Characteristics: The following Antenna Characteristics isolated from surfaces which will alter or change their radiation patterns and efficiency. Current and Voltage Distribution: When an RF signal voltage is applied at some point on an…
Rogowski Coil Integrator Design: If a Rogowski Coil Integrator Design is placed surrounding a current carrying conductor, the voltage signal induced in the coil is vi(t) = M dI(t)/dt where M is the mutual inductance…
