There are generally two types of three-phase energy meters:
– Three-phase three-wire meter: This system is a combination of two single-phase meters. It uses permanent horseshoe magnets.
– Three-phase four-wire meter: This system consists of three coils and three aluminum discs. It is suitable for measuring kilowatt-hours in amp calculations for three-phase motors. Its function is similar to that of a three-phase three-wire meter.
Three-phase energy meters are suitable for commercial and industrial applications. It provides efficient and accurate three-phase motor amperage calculations in areas with heavy electrical loads.
It is often the first choice for metering and determining power efficiency in factories, automated factories, solar power plants, data centers, and many other industries.
It is used to protect valuable equipment from high-voltage damage. It also monitors and provides accurate real-time power consumption data.
This means that the metering system keeps records of three-phase motor amperage calculations for several months. These data can be used for analysis later.
Let's check some of the benefits of installing a three-phase energy meter:
You can use different stages for different rooms. This way, even if one phase fails, you can still power other rooms connected to the 2 functional phases.
You can distribute the load.
It provides real-time and logged power consumption data for better calculation of three-phase motor currents.
