Single-phase electrical energy meters | metering devices with current transformers CT
-
Single-phase electricity meters with current transformers (CT) are professional metering and electrical energy monitoring devices designed for accurate measurement of electricity consumption in single-phase (230 V) systems where direct current connection is not possible or not safe.
Unlike direct-measurement meters, CT-type meters use external current transformers that allow:
measurement of higher currents (e.g., 50 A, 100 A, 200 A and more),
continuous metering without disconnecting cables,
safe integration of measurement into industrial, commercial, and advanced residential systems.
This is an optimal solution for solar power plants, pumps, EV charging points, heat pumps, production lines, and building energy monitoring.Functions and advantages
Indirect measurement via CT – a safe and flexible solution
Accounting for high currents without routing thick cables through the meter
CTs can be installed without disconnecting the power supply
Suitable for automation – integration with BMS, SCADA, PLC
Long-term stability and reliable metering
Clear display for monitoring instantaneous and accumulated dataUsage
For household users: Solar power plants (monitoring of inverter, load, or incoming supply). Monitoring energy consumption of heat pumps, boilers, EV chargers. Accurate allocation of consumption by device.
For electricians: Convenient when reconstructing existing installations. Ability to select CTs according to actual load. Reduced risk when working with high currents.
For engineers / designers: Suitable for commercial and industrial projects. Easy integration into energy management systems. Possibility of remote data reading (Modbus). Accurate energy balance and analysis.Pros
Measurement without direct current connection
Suitable for high currents
Safer installation and operation
Ideal solution for retrofits
Can be integrated into automated systems
Wide choice of CTs according to needsCons
Not all are sold with current transformers (CT)
Not suitable for very simple, low-power installationsSingle-phase electricity meters with current transformers (CT) are a professional, safe, and flexible solution when accurate energy measurement is required in existing or higher-power single-phase systems. They are especially valued where uninterrupted operation, data integration, and wider current ranges are important.
