High Precision Portable Power Quality Energy Analyzer

I.Functional Features

1. The instrument is specially used to detect power quality problems such as waveform distortion, harmonic content, voltage fluctuation and flicker, and three-phase imbalance in the power grid. It also has the functions of electrical parameter testing and vector analysis.

2. Can accurately measure voltage, current, active power, reactive power, phase Angle, power factor, frequency and other electrical parameters.

3. The vector diagram of measured voltage and current can be displayed. Users can get the correct wiring of metering equipment by analyzing the vector diagram.

4. The current is measured by a clamp type transformer. Because the operator does not need to disconnect the current loop when measuring with the tongs current transformer, the measurement can be carried out conveniently and safely. According to the user's different measuring range can be selected with different range of clamp table.

5.It can measure and analyze the ac power quality of the public power network to the client, and its measurement and analysis include frequency deviation, voltage deviation, voltage fluctuation, flicker, allowable unbalance degree of three-phase voltage and network harmonic.

6. Single-phase voltage and current waveform can be displayed, and three-phase voltage and current waveform can be displayed at the same time.

7. All test interfaces have screen lock function to facilitate user reading and data analysis.

8. Load fluctuation monitoring: measure and analyze the fluctuation of power quality of public power grid caused by various electrical equipment under different operating states. Periodically record and store the changing trend of power parameters such as voltage, current, active power, reactive power, apparent power, frequency and phase.

9.Power equipment adjustment and operation process dynamic monitoring, help users to solve problems in power equipment adjustment and operation process.

10. Able to test and analyze dynamic parameters of reactive power compensation and filtering devices in power system and make quantitative evaluation of their functions and technical indicators

11.Different storage interval time can be set to store data continuously at the set interval;

12.Built-in large-capacity data storage, which can be stored at intervals of one minute for more than 18 months, can meet the needs of long-term monitoring test sites.

13.The instrument has USB interface, which can conveniently copy data directly to the background management computer.

14. With powerful data management software, real-time sampling data can be directly uploaded to the background management computer for more comprehensive and rapid processing in the background.

15. With calendar and clock functions, real-time display of date and time. Test data and results can be saved at the same time of on-site testing, and uploaded to the computer through serial port. Data micromanagement can be realized through background management software (optional accessories), with powerful reporting function.

16.Adopt large screen imported color liquid crystal as the display, Chinese operation interface and English characters prompt information, multi-parameter display liquid crystal display interface, man-machine dialogue interface friendly.

17.minutes no-operation LCD automatically enters the power-saving mode to maximize the working time of the battery.

18.Conductive silicone button, good feel, long life, reasonable design, easy to operate.

19.Built-in large-capacity and high-performance lithium-ion rechargeable battery, which can work continuously for more than 10 hours upon full charge.

20.Small size, light weight, easy to carry, can be used for field measurement, also can be used as the standard measurement equipment of the laboratory.
