Product Overview

With the development of electric power industry and the promotion and application of microcomputer integrated automation products, the correctness of the connection of protection circuit and metering circuit directly affects the stability of power system work and the accuracy of electricity metering, which are two very important aspects of power system. Due to the large number of connections between the protection device and the high-voltage metering device, it is easy to cause wrong connection and not easy to be detected (especially for the complex connection of differential protection, sometimes the high and low sides are introduced at the same time, and there are different connection groups, which are very easy to be connected incorrectly. In normal operation, there may be no maloperation or refusal to operate, and there is a great hidden danger). According to the needs of on-site testing, our company has developed a multi-functional vector analyzer in due time. The product integrates multiple functions and has multiple measurement functions. The main measurement functions are: Phase meter function - check the correctness of main transformer differential protection and bus differential protection; Function of electric parameter tester - test necessary parameters of power system; Measuring wiring detector function - to detect the three-phase three wire electric energy measuring wiring; Harmonic content test function - test the harmonic content of voltage and current on site; Oscilloscope function - display the histogram as a simple oscilloscope to observe the test signal waveform. The measuring instrument adopts dsp AC sampling, which can simultaneously measure 3 channels of voltage and 6 channels of current analog quantities. It is the first instrument to display 9 channels of vector on the same screen, with a friendly man-machine interface; The self-developed hand-held structure with mould opening and high-strength engineering plastics are solid and light, easy to use, which greatly facilitates on-site use. They are the right-hand man of power workers.

Main features

1. Three voltage and six current vectors are displayed on the same screen, which is the first in China; For the test of differential protection device, only one connection is needed to complete the drawing of hexagon diagram, which greatly improves the working efficiency; In the case of small space and difficult wiring, the double clamp method can also be used for multiple measurements to finally draw a complete hexagon diagram.

2. Clamp type current transformer wiring is adopted, which is safe and convenient without disconnecting the current loop.

3. The vector analysis of complex protection devices can be carried out to determine whether the wiring is correct, and the correct wiring diagram is given for comparison.

4. It can conduct routine electrical parameter test, and display three-phase voltage, three-phase current, three-phase active power, three-phase apparent power and three-phase phase angle at the same time; It can directly read the voltage amplitude, current amplitude and power values converted to the primary side of the transformer.

5. It can check the wrong wiring of three-phase three wire high-voltage metering device, analyze and judge 48 types of three-phase three wire wiring, and directly give the analysis results; Investigate and deal with the means of stealing electricity by maliciously changing the metering wiring to effectively avoid the loss of electricity charges.

6. It can analyze the harmonics of the measured signal on site, analyze the contents of the 2nd to 21st harmonics, and automatically calculate the total harmonic distortion.

7. Large screen, high brightness color LCD display, full Chinese character graphical menu and operation prompts realize friendly man-machine dialogue. Touching the silicone key makes operation more comfortable and feel better. Wide temperature LCD band brightness adjustment can adapt to winter and summer.

8. Powered by large capacity lithium battery, it can work continuously for up to 8 hours.

9. Users can save the test data in the form of records at any time for centralized and unified management, filing and reference, and can store more than 200 groups of data.

10. The saved records can be uploaded to the background management computer for comprehensive analysis and review.

11. With perpetual calendar and clock functions, it can display the date and time of testing in real time.

12. Small size, light weight, easy to use on site.

13. USB interface is reserved, and instruments can be used to replace USB flash disk and other mobile storage devices.
