Features

1. NAQH3 Portable Microcomputer Power Quality Analysis Set, this instrument is designed to detect ccurrence of waveform distortion grid, high-precision test equipment harmonic content, voltage fluctuation and flicker and unbalanced three-phase power quality issues; also has electrical parameters of the test vector analysis functions.

2. This set can accurately measure a variety of electrical parameters of voltage, current, active power, reactive power, phase angle, power factor and frequency.

3. It also can display measured voltage and current vector, user can draw metering device wiring if correct or not by analyzing vector.

4. Current clamp transformer and can be connected directly measured in two ways. When split core current transformers measure operator, without disconnecting current loop, it can easily and safely be measured; when the values need to be more accurate measurements can be taken directly to a wired connection, to greatest degree of assurance accuracy of test data.

5. Analysis of measurable utility grid supply AC power to the client's quality, its measurement and analysis: frequency deviation, voltage deviation, voltage fluctuation, flicker, phase voltage unbalance and harmonic.

6. This set can display single-phase voltage and current waveforms, can display three-phase voltage and current waveforms.

7. All test interface with a screen lock feature to facilitate reading and analysis of user data.

8. Monitoring of load fluctuations: Measurement and analysis of fluctuations variety of electrical equipment in different operating conditions on utility grid power quality caused. Timing recording and storage of voltage, current, active power, reactive power, apparent power, frequency, phase, and other electrical parameters trends.

9. Adjustment and operation of electrical equipment dynamic monitoring process to help users solve the power equipment Adjustment and commissioning process problems.

10. This analysis set can test power system reactive power compensation and filtering device, can make a quantitative evaluation of dynamic parameters of their functions and technical specifications.

11. You can set a different storage time intervals, according to the set time interval between successive storing data.

12. Built-in high-capacity data storage, at one minute intervals may be stored continuously for 18 months or more, to meet the needs of long-term monitoring of test point.

13. The instrument includes a USB interface, you can easily copy the data directly to backstage management computer.

14. It have powerful data management software, real-time sampling data can be uploaded directly to the background management computer, in background a more comprehensive and more rapid treatment.

15. with calendar, clock function, real-time display date and time. In the field of detection while preserving test data and results, and uploaded to computer through serial port, computerized data management through background management software (optional), with strong reporting capabilities.

16. Use imported large-screen color LCD as display, English & Chinese interface, English and Chinese characters with message, multi-parameter display LCD interface, friendly interface English & Chinese man-machine dialogue.

17. Have five minutes no operation LCD automatically turns off, in order to maximize the extended battery life.

18. The conductive silicone keys, feel good, long life, reasonable design, easy to operate.

19. Built-in high-capacity, high-performance lithium-ion rechargeable battery, full power continuously for more than six hours.

20. Small size, light weight, easy to carry, both for on-site measurements, can also be used as laboratory standards metering equipment.
