GSDN-Y Portable Power Quality Analyzer



DARUI Electric recommends this for you

       

With the vigorous development of our national economy, the annual increase in electricity consumption, and the sharp increase in power load, the continuous growth of various types of electrical loads (especially impact and nonlinear load capacities) has greatly affected the quality of power supply in the grid. This is prominently manifested in power quality issues such as increased harmonic content in the grid, severe waveform distortion, voltage fluctuations and flicker, and three-phase imbalance exceeding allowable limits. To solve these problems, it is first necessary to accurately measure and analyze the above phenomena. Based on this demand, our company has timely developed and produced the DSDN-Y Portable Power Quality Analyzer.

       GSDN-Y Portable Power Quality Analyzer is a multifunctional test instrument that integrates power quality analysis, electrical parameter testing, and power vector analysis. The instrument is equipped with high-precision, high-linearity voltage transformers and current transformers, enabling high measurement accuracy for various parameters. It is also equipped with clamp-type current transformers, making on-site wiring simple. It uses a large-screen imported color LCD as the display, with a Chinese operation interface and Chinese prompt information, and a multi-parameter display LCD interface. The human-machine dialogue interface is friendly, and the vector diagram display and wiring judgment provide a reliable basis for checking the correctness of the circuit. The instrument has a built-in large-capacity data storage that does not lose data when power is off, allowing on-site calibration data to be saved. It can provide background computer management software to upload results to a computer, achieving computerized management.

Main Features:

1. Small size, light weight, and easy to carry;

2. Built-in high-performance lithium-ion battery allows the instrument to work continuously for 10 hours without external power, facilitating on-site testing;

3. Multi-parameter: can simultaneously measure voltage, current fundamental wave, 2nd to 64th harmonics, phase, frequency, power, power factor, and other parameters;

4. Can perform vector analysis of metering circuits and protection device circuits;

5. Can measure total harmonic distortion rate;

6. Can measure short-term flicker and long-term flicker of each phase voltage and current;

7. Can measure voltage unbalance;

8. Can display real-time waveforms of each phase parameter, serving as a simple oscilloscope function;

9. Can set different storage intervals and continuously store data according to the set time interval;

10. Built-in large-capacity data storage can continuously store data for more than 18 months at 1-minute intervals;

11. 5.7-inch large-screen color LCD display;

12. Harmonic measurement, judging whether harmonics exceed standards according to national standards, at a glance;

13. Equipped with a micro printer, test results can be printed on-site at any time;

14. Data can be stored on a USB drive for historical inquiry.

15. Can be equipped with dedicated data analysis and management software to analyze and process test results, understand the periodic variation patterns of power quality and load at the measured point, and play an important role in helping power workers understand user power quality and take corresponding treatment measures.
