Zc-630 harmonic analyzer is a multi-functional measuring instrument developed by our company with the latest technology. It adopts the button type operation, can automatically switch the measuring range, maintain the measured data, store the measured data, realize the large capacity storage, and output the vector diagram, with very powerful functions.
ZC-630 harmonic analyzer is very suitable for electric energy measurement, power consumption inspection, power audit, transformer maintenance, relay protection and other differential detection, start-up test field use.
1. Function introduction
This function displays three-phase voltage in the form of vector (phasor) diagram, the amplitude and phase of three-phase current, the magnitude of voltage amplitude is proportional to the length of voltage vector, and the magnitude of current amplitude is proportional to the length of current vector.
On the right side of the interface, the amplitude and phase of the voltage and current are displayed digitally, and whether the voltage phase sequence and current phase sequence are correct is automatically judged. The amplitude value is represented by a white square, and the phase sequence cannot be determined. The Red Square indicates that the phase sequence is wrong, and the green square indicates that the phase sequence is correct. The interface is shown in Figure 4:

2. Operation method
Data retention function: the retention function keeps the measured values of parameters on the screen and the vector map unchanged, which is convenient for users to read and analyze. Press F2 key to maintain and cancel the current measurement result.
Switch to the three-phase volt ampere interface: in this interface, press F1 key, and the instrument returns to the three-phase volt ampere interface.
Switch to the single test interface: in this interface, press F4, and the instrument will jump to the single test interface.
Switch to display setting interface: in this interface, press F3, and the instrument will jump to display setting interface.
In this interface, the angle positive direction, zero sequence position, reference angle of vector graph can be realized, and whether UA, UB, UC, IA, IB and IC vectors are displayed. The interface is shown in Figure 5.

Use the ←, → keys to move to the item to be changed, and use the ↑, ↓ keys to change the item options.
According to the user's habit, the positive direction of the angle can be set as the positive direction or the negative direction, the 0 angle can be set as the 12 point direction or the 3 point direction, and the reference amount can be set as 0 ° or 330 °. You can set whether to display UA, UB, UC, IA, IB, IC. After changing the parameter settings, you can press F3 to save the settings, or press F2 to directly return to the default setting parameters, and press F1 to return to the vector diagram interface to view the setting results.
The above is the introduction of vector diagram measurement method of zc-630 harmonic analyzer. Do you understand? If you have any questions, you can always consult our online customer service.
