Concept of Power Quality Analyzer

In generally speaking, the Power Quality Analyzer refers to the machine that can supply high-quality power, including voltage quality, current quality, power quality.It is different Voltage, current, or frequency deviation that causes electrical equipment failure or malfunction, including frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase imbalance, transient or transient overvoltage, waveform distortion.

How To Facilitate The Observation Of Small Signals?

图片
How to set up the high sensitivity of the  Spectrum Analyzers  to facilitate the observation of small signals? A: first, set the corresponding center frequency sweep width (span) and reference level according to the size of the small signal under test;Then, the attenuation value is gradually reduced in the absence of any overload warning in the spectrum analyzer.If the SNR of the measured small signal is less than 15db, RBW will be gradually reduced. The smaller RBW is, the lower the base noise of the spectrum analyzer will be, and the higher the sensitivity will be. If the spectrum analyzer from  Spectrum Analyzer Supplier  has pre-amplifier, opening pre-amplifier and pre-release can improve the noise coefficient of the spectrum analyzer, thus improving the sensitivity. For small signals with low signal-to-noise ratio, it can reduce VBW or adopt trajectory average to smooth the noise and reduce fluctuation. It should be noted that the measurement result o...

What is the application of signal generator

图片
A  signal generator  is a device that provides electrical signals of various frequencies, waveforms and output levels. Signal generator, signal modulation functions: signal modulation refers to the modulated signal, amplitude, phase or frequency change of the carrier signal frequency information is embedded into the high frequency, the signal can be transmitted from voice to data, and to any video signal. Signal generator has a wide range of applications in the field of production practice and technology. We can also supply the high quality  Universal Frequency Counter,   Digital Multimeters  etc. If you need, welcome to contact us.

Power Quality Analysis Method

图片
We are a leading  Power Quality Analyzer China  Supplier. Today , let we tell the Power quality analysis method. Power quality is a very important part of the future power grid construction. Nowadays, the transformation of distribution network and the upgrading of rural power grid are in full swing, and the quality of power is also receiving much attention. The power quality problems caused by various disturbances in the power system can be mainly divided into two categories: steady state events and transient events. Steady-state power quality problems are characterized by waveform distortion, including harmonics, interharmonics, waveform sags, and noise. Transient events are usually characterized by spectrum and transient duration, which can be divided into pulse transients and oscillations. Two major categories. The analysis methods of power quality are mainly time domain simulation methods, frequency domain analysis methods and transformation based methods. In fact, ...
