Display:
Considering the importance of displaying current, voltage, frequency and other important parameters of the system, a device that can do this permanently and continuously is needed. In practice, in order to be able to display all the recorded values in a device to analyze the power of the system and the power consumption of the desired location, voltage displays must be used.
The function of these devices is that it has several terminals to connect the power supply of the device itself, CT wires to measure the current of the phases and connect all three phases to measure the voltage. In fact, by connecting the connections mentioned above, this device will be able to display all the desired items.
Of course, the displays are different in terms of features. Some displays are only capable of measuring three-phase and single-phase voltages, as well as displaying three-phase tolerant current consumption. In addition to measuring the average current and True Rms of three phases and three-phase and single-phase voltages, some monitors are capable of measuring frequency. Some of the devices are also able to be networked. Then we have to choose the desired device according to our needs.
## The things that should be known when buying screens are:
##
## 1- Display power supply voltage
##
## 2- Accuracy of current measurement
##
## 3- Ability to measure True Rms current
##
## 4- The number of indicators
##
## 5- Appearance and type of installation
