How to correctly use the three-phase phase volt-ampere meter - Yangzhou Darui
Darui Electric recommends for you
Three-phase phase volt-ampere meter (also known as volt-ampere meter) many people have not heard of it. This meter is a handheld dual-channel fully automated and high-function instrument that can achieve high-precision measurement. Let's learn about the specific usage of the three-phase phase volt-ampere meter.
The characteristics of the three-phase phase volt-ampere meter are quite obvious. This instrument mainly uses new microprocessor technology and digital signal processing technology, and also uses direct AC sampling methods to achieve measurement values of power parameters, such as measuring the effective values of voltage and current, power frequency, and their relationships. It can not only determine the connection group of transformers, inductive and capacitive resistances, but also effectively test secondary circuits and bus differential protection systems. It is necessary to check whether the wiring of the electric energy meter is accurate. However, when using this volt-ampere meter, it can provide a safer, more accurate, or more convenient new-type power instrument for electricity inspection personnel. Its applicable range is also very wide. It can be used in many power departments, petrochemical departments, metallurgical departments, iron ore enterprises, industrial and mining enterprises, research institutes, and quality departments. It is particularly suitable for electric energy metering systems and relay protection systems.
Now we have a certain understanding of the usage and characteristics of the three-phase phase volt-ampere meter. This product adopts a large-screen high-backlight display, and can clearly see all working states and test parameters. The operation is very convenient. It can also measure voltage, current, and phase of two circuits, as well as measure the frequency of the power grid. Before use, we should pay attention to determining inductive and capacitive circuits, and then measure the phase sequence of three-phase voltage.
