Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
XY Recorder Working: XY Recorder Working - In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased…
True RMS Voltmeter: True RMS Voltmeter - Complex waveform are most accurately measured with an rms voltmeter. This instrument produces a meter indication by sensing waveform heating power, which is…
Chopper type DC Amplifier Voltmeter (Microvoltmeter): Chopper type DC Amplifier Voltmeter the dc input voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back…
Electrodynamometer Instrument: Electrodynamometer Instrument - The D'Arsonval movement responds to the average or dc value of the current flowing through the coil. If ac current is sought to be measured,…
Difference Between SVC and Statcom: Difference Between SVC and Statcom may be noted that in the normal linear operating range of the V-I characteristic and functional compensation capability of the…
Optimal Load Flow Solution: The problem of optimal real power dispatch has been treated in the earlier section using the approximate loss formula. This section presents the more general problem…
