Power Quality Monitoring Equipment

1.Power Quality Monitoring Equipment Functional Features

Power Quality Monitoring Equipment Power quality monitoring and energy efficiency evaluation for power systems and equipment under different operating conditions.

1.The instrument is a high-precision testing instrument specially used to detect electrical energy quality problems such as waveform distortion, harmonic content, and three-phase imbalance in the power grid; it also has the functions of electrical parameter testing and vector analysis.

2.It can accurately measure various electrical parameters such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc.

3.A vector diagram of the measured voltage and current can be displayed.Users can analyze the vector diagram to find out whether the wiring of the metering device is correct.

4.The current is measured using a clamp transformer.Because when using clamp current transformer to measure, the operator does not need to disconnect the current circuit, so that the measurement can be carried out conveniently and safely.Depending on the user's measurement range, you can choose clamps of different ranges.

5.The AC power quality supplied to the user terminal of the public power grid can be measured and analyzed, and its measurement and analysis: frequency deviation, voltage deviation, three-phase voltage allowable imbalance and grid harmonics.

6.It can display single-phase voltage and current waveforms and can display three-phase voltage and current waveforms at the same time.7.All test interfaces have screen lock function to facilitate users to read and analyze data.

8.Can measure short-term flicker Pst and long-term flicker Plt.

9.Load fluctuation monitoring: measure and analyze the fluctuations caused by various electrical equipment to the power quality of the public power grid under different operating conditions.Timely record and store the changing trends of power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.

10.Record the active and reactive power consumed at the test point.

11.Dynamic monitoring of power equipment adjustment and operation process help users solve problems that arise during power equipment adjustment and operation.

12.Able to test and analyze the dynamic parameters of reactive power compensation and filter devices in the power system and make quantitative evaluations of their functions and technical indicators

13.Different storage intervals can be set and data can be continuously stored according to the set time intervals;

14.Built-in large-capacity data memory, the storage interval can be adjusted from 3 seconds to 10 minutes; it can be continuously stored for more than 18 months at a time interval of 1 minute, which can meet the needs of long-term monitoring and testing test points.

15.The instrument has a USB interface, which can easily copy data directly to the background management computer.

16.Cooperating with powerful data management software, real-time sampled data can be uploaded directly to the background management computer, and more comprehensive and faster processing is carried out in the background.

17.Optional WIFI (Bluetooth) module and remotely control the instrument using a tablet or smartphone.

18.It has perpetual calendar and clock functions, and displays date and time in real time.Test data and results can be saved while on-site inspection, and uploaded to the computer through the serial port.Data microcomputer management can be realized through background management software (optional accessories), and has powerful reporting functions.

19.The large-screen imported color LCD is used as a monitor, and the Chinese operation interface is equipped with Chinese character prompt information and a multi-parameter display interface, and the human-computer dialogue interface is friendly.

The LCD display will automatically enter power-saving mode without operation in 20.3 minutes to maximize the battery working time.

21.Conductive silicone buttons have good feel, long life, reasonable design and convenient operation.

22.Built-in large-capacity, high-performance lithium-ion rechargeable battery, fully charged and continuously working for more than 10 hours.23.Small in size, light in weight, easy to carry, can be used for on-site measurement and use, or as a standard metering equipment in the laboratory.
