PS-DN4 Power Quality Analysis Instrument

Core Description

Introduction

1. Multi-channel measurement: simultaneous measurement of 4 voltage channels and 4 current channels.
2. Electrical parameter measurement: it can measure voltage amplitude, current amplitude, phase, frequency, active power, reactive power, power factor and other parameters at the same time;
3. It can measure the voltage and current harmonic content of 2-64 times;
4. It can measure the interharmonic content of 0.5-31.5 times voltage and current;
5. It can measure the total harmonic distortion rate of voltage and current;
6. Measurable and short-term flicker (PST), long-term flicker (PLT), and voltage fluctuations;
7. It can measure positive sequence voltage, negative sequence voltage, zero sequence voltage, and voltage unbalance degree;
8. It can measure positive sequence current, negative sequence current, zero sequence current, current unbalance degree;
9. Transient parameter measurement function, with the event recording function of voltage swells and drops, and the recording function is automatically activated at the same time to record the occurrence time of the event and the actual waveforms of the five cycles before and after the occurrence;
10. With oscilloscope function, real-time waveform display of voltage and current size and distortion, and voltage and current waveforms can be zoomed on the instrument;
11. Hexagonal diagram display function, which can perform vector analysis of metering circuit and protection device circuit, and check for wrong wiring of metering device; in the case of three-phase three-wire wiring, it can automatically judge 48 wiring methods; automatic calculation of supplementary power is convenient to use The personnel calculate the supplementary power for users with wiring problems.
12. Optional large clamp meter can be used to measure the transformation ratio and angular difference of low-voltage current transformers;
13. The harmonic content can be displayed in the form of a histogram with good visual effects;
14. Built-in large-capacity data storage, (storage interval 1 second-1000 minutes optional) can be stored continuously for more than 18 months at a time interval of 1 minute;
15. 10-inch large-screen color LCD display 1280×800;
16. The capacitive screen touch operation is similar to the operation of a tablet computer and a smart phone, which is simple and easy to learn;
17. Support mouse operation, adapt to operators with different habits;
18. When measuring harmonics, it can automatically judge whether the content of each harmonic exceeds the standard according to the national standard and give a prompt, which is clear at a glance;
19. Harmonic content rate national standard query function, which can query the allowable value of the national standard;
20. With a frequency measurement range of 42.5Hz-69Hz, it can measure 50 and 60 power systems.
21. It can be equipped with special data analysis and management software to analyze and process the test results. It can grasp the power quality and periodic changes of the load at the measured point, and it is irreplaceable for the power staff to understand the user’s power quality and take corresponding processing measures. The role of
22. The analysis software can generate professional power quality analysis reports in accordance with the requirements of the national standard;
23. The instrument has a screen capture function, and the display data of any screen can be manually saved in the form of pictures;
24. Built-in high-performance lithium-ion battery, automatically enters the power saving mode, which can make the instrument work continuously for more than 10 hours without external power supply, which is convenient for on-site testing.
