Three-phase electricity meters | energy metering devices
-
Three-phase electricity meters are professional electrical metering devices designed for accurate measurement of electrical energy, power, and other electrical parameters in three-phase (3F) electrical systems. These devices are widely used in industry, commercial facilities, apartment buildings, energy projects, and automated control systems.
Modern three-phase meters are not limited to kWh calculation only – they allow monitoring of voltages, currents, active and reactive power, power factor (cos φ), and often support Modbus, M-Bus, or pulse outputs, making them easy to integrate into BMS, SCADA, PLC, and remote monitoring systems.
Functions and capabilities
Accurate three-phase electricity metering (kWh, kvarh)
Power and load analysis – helps optimize electricity consumption
Remote reading via Modbus / M-Bus
Operation with current transformers (CT) – suitable for high currents
Real-time measurements – useful for diagnostics and energy audits
Integration into automated systems (BMS, SCADA, EMS)
Tariff-based metering (in some models)
UsageFor household users / building owners: Monitoring electricity consumption in individual houses with a three-phase supply. Clear distribution of consumption by phases.
For electricians: Reliable solution for panel assembly. DIN rail / panel mounting. Compatibility with CTs and controllers.
For engineers / energy specialists: Analysis of energy flows. Power balancing and loss identification. Integration into energy management systems.
For business and industry: Separate electricity metering for production lines, workshops, tenants. Energy cost control. Data for energy efficiency reports.
ProsAccurate three-phase electricity metering
Ability to work with high currents via CT
Wide range of communication protocols
Suitable for both small and large facilities
Helps reduce electricity costs and optimize loads
ConsMore complex installation compared to single-phase meters
CT-based models require correct transformer selection
Advanced models are more expensive than basic onesThree-phase electricity meters are indispensable solutions for modern electrical metering and energy management, enabling not only measurement but also analysis and optimization of electricity consumption. Whether it is a private property, an industrial enterprise, or a commercial building – a properly selected three-phase meter provides clear data, control, and real long-term benefits.
