Decoupled Load Flow Methods (DLF): An important characteristic of any practical electric power transmission system operating in steady state is the strong interdependence between real powers and bus voltages angles and between reactive powers and…
Electric Traction Services: Electric Traction Services can be broadly classified as: Electric Trains. Electric buses, trams (or tramways) and trolleys. Battery driven and solar powered vehicles. Electric Trains: Electric trains run on fixed rails. They…
Addressing Modes of 80386 Microprocessor: The 80386 can operate in all the addressing modes which were available with the 80286 processor. The 80386 processor can also operate in all addressing modes of 80286 with 32-bit…
High Voltage Test on Insulators: The High Voltage Test on Insulators that are normally conducted are usually subdivided as Type tests and The routine tests. Type tests are intended to prove or check the design…
Impatt Diode Working: IMPATT Diode Working is a combination of delay involved in generating avalanche current multiplication, together with delay due to transit time through a drift space, provides the necessary 180° phase difference between…
Triggered Sweep CRO: Triggered Sweep CRO - The continuous sweep is of limited use in displaying periodic signals of constant frequency and amplitude. When attempting to display voice or music signals, the pattern falls in…
Generation of DSBSC Signal using Balanced and Ring Modulator: DSBSC signal can be obtained by simply multiplying the modulating signal with the carrier signal. By simple multiplication of Vc sin ωct and Vm sin ωmt, we have the…
Arithmetic Instructions in 8051: The Arithmetic Instructions in 8051 of Basic Assembly Language Programming are ADD, ADDC, SUBB and DA The ADD instruction adds a byte variable with the accumulator, leaving the result in the…
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.…
Differential Instrumentation Amplifier Transducer Bridge: Figure 14.25 shows a simplified circuit of a Differential Instrumentation Amplifier Transducer Bridge. In this circuit a resistive transducer (whose resistance changes as a function of some physical energy) is…
