The role of three-phase digital voltmeter in energy consumption monitoring system

Three-phase digital voltmeter
Now the state vigorously promotes energy-saving renovation projects in factories, buildings, hotels, and public buildings. In order to make energy saving and consumption feasible, energy consumption monitoring systems must be built first. The energy consumption monitoring system mainly over-measures water consumption, gas consumption, and power consumption. The most important thing is the power consumption, and the power consumption of each branch must be monitored. The old-fashioned meter has a single function, low accuracy, and communication. The interfaces are not rich and cannot transmit remote data.
At this time, the three-phase digital display voltmeter came into being. The three-phase digital display voltmeter produced by Renhe Intelligent Technology is rich in functions and can monitor the current, voltage, power, power factor, active power, and reactive power in high and low voltage power grids. Power parameters such as degree, frequency, zero-sequence current, and harmonics. Accuracy current and voltage can reach 0.2 level, power accuracy level can reach 0.5, 0.2S level.
The most important thing is that the communication interface is very rich. There are RS485 communication interface, Profibus communication interface, analog 4-20mA output interface, and switch input and output interface, which makes background monitoring simple and effective.
