Zc-630 power harmonic analyzer is also known as three-phase harmonic analyzer. It can be used to measure power harmonic, three-phase voltage, three-phase current 1-63 harmonics, and display odd or even harmonics in list or spectrum.
The following is an introduction to the harmonic test function of zc-630 power harmonic analyzer:
1. Function description
The power measurement interface shows the amplitude, proportion, phase angle, total effective value, total harmonic distortion rate (%), fundamental frequency of 1-64 harmonics of three-phase voltage and current. It can be displayed in the form of list, spectrum chart, even harmonics or odd harmonics. As shown in Figure 1.
Figure 1
2. Operating instructions
In the list display interface, use ←, → to turn pages.
Data retention function: the retention function keeps the measured values of parameters on the screen unchanged, which is convenient for users to read and analyze. Press F2 key to maintain and cancel the current measurement result.
Switch measurement channel: Press F1 key to realize channel switching of UA / UB / UC / IA / Ib / IC.
Switch the number of display harmonics: press F3 to display all / odd / even harmonics. The effect is shown in figures 2 and 3.

Figure 3
Switch to the spectrum display interface: press F4, and the instrument switches to the amplitude spectrum display page, which can display the spectrum of 1-64 harmonics, and can display even harmonics or odd harmonics separately. It can also display total effective value and total harmonic distortion rate. As shown in Figure 4.

3. Operating instructions of spectrum display interface
Press F1 key to switch the sampling channel, which is UA → UB → UC → IA → IB → IC.
Press F2 key to maintain and cancel the current measurement result.
Press F3 key to switch the display times of harmonics, which are all displayed → odd harmonics → even harmonics.
Press F4 key, the instrument will jump to the harmonic measurement list display interface shown in Figure 1.
Zc-630 three-phase harmonic analyzer is easy to operate and has powerful functions. It is very suitable for the field use of differential detection and start-up test, such as power metering, power inspection, power inspection, transformer maintenance, relay protection, etc. It can be used as training tool and teaching instrument for wiring discrimination in electric power colleges. At the same time, it is also suitable for large-scale power consumption enterprises such as chemical industry, metallurgy, mining, railway, etc. It's worth buying~
