Nonlinear Distortion Measurements: One of the methods of Nonlinear Distortion Measurements consists of simultaÂneously applying two sinusoidal voltages of different frequencies to the amplifier input and observing the sum, difference…
Signal Conditioning System: Signal Conditioning System - The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first stage…
Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot…
What is Wave Analyzer?: It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure the amplitude…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive…
Voltage Stability Analysis: The voltage stability analysis for a given system state involves examining following two aspects. Proximity to voltage instability: Distance to instability may be measured in terms of…
What is Load Forecasting in Power System?: Load Forecasting in Power System plays an important role in power system planning, operation and control. Forecasting means estimating active load at various…
