Three-phase electricity meters | energy metering devices with current transformers CT
-
Three-phase electricity meters with current transformers (CT) – professional electrical metering and analysis devices designed for accurate measurement of electrical energy (kWh), power (kW), current (A), voltage (V), and other parameters in medium- and high-power three-phase systems.
These meters are widely used in industry, commercial buildings, solar power plants, infrastructure facilities, and distribution boards where direct current connection is not possible or not safe. By using external current transformers (CT), a wide measurement range, high accuracy, and maximum safety are ensured.
What is CT (current transformers)?
CT (Current Transformer) – a current transformer that converts high line current (e.g., 100A, 400A, 1000A) into a standard measuring current (usually 5A or 1A) suitable for the meter.
Functions and capabilities
High-accuracy metering with CT – suitable for high loads
Remote data reading (via RS485 / Modbus)
Integration with BMS, SCADA, EMS systems
Suitable for solar, wind, and hybrid systems
Instantaneous and accumulated data analysis
Individual phase monitoring – imbalance detection
Durable and reliable constructionUsage
For household / advanced users: Monitoring energy of individual solar power plants (PV). Accurate consumption and production balance. Metering by individual lines or buildings.
For electricians: Convenient DIN rail / panel mounting. Safe operation – no direct connection to high current. Flexible CT selection according to the project.
For engineers / designers: Solutions for industry, commerce, energy sector. Data transmission to control and analysis systems. Ability to optimize energy consumption.
For industry and business: Energy metering of production lines. Energy distribution for tenants / departments.Pros
Allows measurement of very high currents
High level of safety
High accuracy and stability
Compatible with various CTs
Suitable for automated and smart systems
Long service life, designed for continuous operationCons
Not all are sold with current transformers (CT)
Installation is more complex than direct metersThree-phase electricity meters with current transformers (CT) – metering devices when an accurate, safe, and professional solution is required for high-power three-phase systems. Suitable for industry, commercial facilities, renewable energy, and advanced homes where not only metering but also energy analysis and optimization are important.
