The power analyzer is mainly a high-precision instrument that measures electrical parameters such as voltage, electric mass current power, power band travel factor, phase, energy, harmonic analysis, flicker analysis, spectrum analysis, etc., as long as it is used in industries that need to measure these parameters.

1. Clarify the self-rate range of the working frequency of the measured object, and select the power analyzer with the appropriate sampling rate.

2. Clarify how many measurement channels need to be used to determine the object to be measured, and compare the three-phase motor (3 channels), photovoltaic inverter, DC to AC (4 channels), and three-phase inverter AC to AC (6 channels).

3. Measure the size and frequency range of the current, and select the current sensor with appropriate range and bandwidth.

4. Confirm whether the mechanical power of the motor needs to be measured.

The PW6001 has a sampling rate of 5MHz, a resolution of 18bit, a voltage input of up to 1500V, and a variety of current sensors, which can meet the power measurement and analysis of high-power and high-frequency electrical products.

Find an imported power analysis instrument brand to consult and buy. It is recommended that Yinfei Electronics take a look at the official website.

1. From the comparison of the above figure, in terms of volume, the power meter can be done in the style of a handheld multimeter, or a relatively small desktop, the power analyzer is generally desktop, according to the different channels The volume difference is relatively large, the largest is the seven-channel power analyzer, Germany and Japan have.

2. In terms of function, the power meter focuses on the reading of voltage and current power, and the general bandwidth sampling will not be too high, which is suitable for the test and measurement of power consumption of power frequency electronic equipment, and the power analyzer focuses on analysis, so the bandwidth can be up to 10m, the sampling can be to, and the refresh can be up to 10ms, in addition to supporting graphic display, some oscilloscope functions, in addition to harmonic analysis, event triggering, filtering and other functions that the power meter does not have.

3. The gap is too big, the power meter is within a few thousand to 1-20,000, the power analyzer imported brand 4 channels are generally more than 200,000, and the 7 channels are 30-400,000.

Both are measuring devices whose main purpose is to measure power, and there is no strict distinction between them.

If it were not for the development of frequency conversion technology, if there was no application of nonlinear equipment, and if the measured quantity was sine wave or DC, it is estimated that the title of power analyzer would not appear.

In contrast, the function of the power meter is relatively simple, mainly measuring the effective value of voltage and current, active power, reactive power and other parameters, mainly used for power frequency or DC parametric measurement.

A power analyzer has all the features of a power meter. Since the measured object often contains harmonics, the characteristics of voltage and current signals cannot be measured by just one parameter of the RMS. Therefore, power analyzers often also have functions such as real-time waveform and harmonic analysis.

For voltage and current, in addition to measuring its RMS, it is often measured or analyzed that its fundamental RMS is also measured, and for power parameters, in addition to the active power, the fundamental power and the power of each harmonic are also measured or analyzed.

1. Power analyzer refers to an instrument used for electrical parameter measurement, which is generally used to measure voltage, current, and power-related values, also known as power tester.

2. The measurement principle can be understood simply as p=u*i, and a single will design complex formula operations and AD conversion.

3. The general mainstream power is now 2-3U, 1-7 channels, rack or desktop, and portable.

4. The most important point of attention is that the sensor must be supplied with power first, and then tested, and the other is to choose a power analyzer to polish your eyes, because there are too many influencing factors.

The power analyzer is used to measure and analyze the power of electricity, and the relevant measurement quantities include voltage, current, frequency, power (active and reactive), power factor, etc.

Compared with traditional analog or digital power meters, power analyzers are more used in variable frequency power testing, which is relatively complex to measure and has relatively many functions. Generally, in addition to conventional power measurement, it often has harmonic analysis, real-time waveform display, data storage and so on.

As for the types, there is no clear and uniform way of dividing them. In my opinion, at present, a large number of power analyzers at home and abroad, some are crowned with high precision, some are crowned with broadband, and their basic ideas are similar, and the main differences are in function, performance and accuracy indicators.

As for the precautions:

1. See if it can meet your testing needs, take your testing needs as the technical conditions, and see if its accuracy indicators can meet your requirements under these conditions.

2. See if you can purchase the sensor that matches it, whether the sensor can meet your accuracy index, and how to evaluate the accuracy index after the two are combined.

Hunan Yinhe Electric and the National University of Defense Technology jointly developed anyway broadband power test system, is a new type of power analyzer. The biggest difference from other power analyzers is:

1. Provide an overall solution, without the need for users to configure sensors and related lines.

2. Adopt front-end digital technology, digital transmission, strong anti-interference performance.

3. The technical indicators are simple, easy for users to understand, and not misleading! Don't hide it!

We have used an electrical power analyzer, the model is SST-300. It can measure the active power, reactive power, apparent power, harmonics, frequency, voltage, current, and electrical energy of the electrical system. and all other electrical parameters.

There are also some testers for mechanical power, but all of them are tested by converting to electrical parameters. After all, electrical measurements are the easiest and most accurate.

FYI.

First of all, the power analyzer has no dead time, and the oscilloscope has a dead time, which is also the reason why the sampling rate of the power analyzer is not as high as the oscilloscope, the power analyzer calculates the input signal at each moment, and the oscilloscope collects the waveform through the trigger; Secondly, the oscilloscope can not accurately measure the alternating current power, which is the biggest difference, because when the oscilloscope uses voltage probe and current for data acquisition, the delay between the two channels reaches the millisecond basic, and the phase angle error is large, which affects the calculated power factor; For example, the synchronization clock of ZLG Zhiyuan Electronics PA6000 power analyzer is as high as 100MHz, which ensures that the phase synchronization error is within 10ms.

The difference between a power analyzer and an oscilloscope is still very big, the oscilloscope is mainly used to analyze the details of the waveform, so his sampling rate is very high, so his accuracy will be relatively low; The power analyzer is mainly used for power analysis, it is a steady-state test instrument, the sampling rate is not high, so that he will measure the electrical parameters with high accuracy. The main function of the oscilloscope is waveform analysis, it can not directly measure large voltage, can not measure current, if you need to measure, then you need to use a high-voltage differential probe and a current sensor, the power analyzer can measure large voltage, some power analyzers can also measure current, can calculate power, harmonics, etc., these are not possible with the oscilloscope.

The oscilloscope can not accurately measure the alternating current power, which is the biggest difference, because when the oscilloscope uses voltage probe and current for data acquisition, the delay between the two channels reaches the millisecond basic, and the phase angle error is large, which affects the calculated power factor; , while the power analyzer has a high-speed synchronous clock between the voltage channel and the voltage channel.

The power analyzer is mainly used to measure the motor efficiency and total efficiency of power conversion devices such as engines, motors, motors, and transformers. At present, power analyzers are widely used in hybrid electric vehicles, electric vehicles, solar power generation and other environmentally friendly fields. It has brought unprecedented value to mankind.

Power analyzers can effectively help people in the development of motors and performance evaluation, so as to reduce the occurrence of failures. It is also possible to measure power consumption and power generation by means of DC, effective current, and power calculation functions. Power analyzers are becoming more and more important in our lives because they can solve some of the problems that exist in our lives.
