Zc-650 loop vector analyzer is also known as six phase protection loop vector tester and wireless relay protection vector analyzer. It is composed of two hand-held measuring terminals, which can measure six voltage, current amplitude and phase synchronously, and can also be used as a three-phase volt ampere phase meter.
Zc-650 wireless relay protection vector analyzer adopts key type operation, can automatically switch the range, realize large capacity storage, and can display vector diagram, which is very suitable for differential detection, start-up test field use such as electric energy measurement, power inspection, power inspection and 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.
This paper introduces the three-phase volt ampere measurement method of zc-650 loop vector analyzer.
The three-phase volt ampere measurement function of zc-650 loop vector analyzer is mainly used to measure the basic parameters of three-phase voltage and three-phase current. Specific parameters include three-phase voltage effective value, three-phase current effective value, frequency and three-phase voltage, current, voltage and current phase, power factor. The interface is shown in Figure 3:
Figure 3
Note: the frequency here shows the frequency of phase I voltage. To measure the frequency of phase I and phase II, please use the "single channel measurement" function.
Here are the instructions:
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 to the main interface: Press F1 to switch the instrument to the main interface.
Switch to the true RMS measurement state: press F3 key, the instrument will switch to the true RMS state. By default, the voltage displayed on the interface, the current amplitude is the fundamental amplitude, and switch to the true RMS measurement state, the voltage displayed on the interface, the current amplitude is the true RMS.
The above is the three-phase volt ampere measurement method of zc-650 loop vector analyzer. Have you mastered it? If you don't understand, you can always consult our customer service personnel for details.
