380V 3 Phase Electric Meter
Looking for a 380V 3 Phase Electric Meter that matches your electrical system, current range and communication requirements? This product range includes three-phase meters for 3-phase 3-wire and 3-phase 4-wire networks, with direct-connected and current transformer-operated configurations available for different load capacities.
Depending on the selected model, the meter can measure active energy, reactive energy, voltage, current, active power, reactive power, apparent power, power factor, frequency, demand and other electrical parameters. Options such as DIN rail installation, LCD display, RS485 Modbus RTU, pulse output, multi-tariff metering and bidirectional energy measurement can support distribution panels, factories, commercial buildings, solar systems and equipment-level submetering.
Before selecting a meter, confirm the system voltage, wiring configuration, maximum current, CT secondary output, accuracy class, installation dimensions and required communication protocol. The correct configuration helps prevent inaccurate readings caused by incorrect phase wiring, CT polarity or transformer ratio settings.

Frequently Asked Questions
It depends on the rated voltage range of the specific meter. In many three-phase systems, 380V or 400V refers to the line-to-line voltage, while the phase-to-neutral voltage is approximately 220V or 230V. Some meters are designed with a wider operating voltage range and can support both nominal systems, but the datasheet must be checked before installation.
The meter configuration must match the actual electrical network. A three-phase four-wire system includes L1, L2, L3 and neutral, while a three-phase three-wire system does not use a neutral conductor. Using the wrong wiring configuration can cause incorrect voltage, power and energy readings.
A direct-connected meter carries the circuit current through its terminals and is normally used when the load current is within the meter’s rated capacity. A CT-operated meter receives a reduced current signal from external current transformers and is more suitable for high-current feeders, large distribution panels and retrofit projects.
Depending on the model, a three-phase meter may measure active energy in kWh, reactive energy in kVArh, phase voltage, line voltage, current, active power, reactive power, apparent power, power factor, frequency and maximum demand. Advanced models may also provide harmonics, phase imbalance, multi-tariff and bidirectional energy data.
Models equipped with RS485 and Modbus RTU can transmit measurement data to an energy management system, building management system, PLC, gateway or SCADA platform. The communication address, baud rate, parity and register mapping must be configured correctly to establish reliable data transmission.
Incorrect readings are commonly associated with reversed CT polarity, mismatched voltage and current phases, an incorrect CT ratio, the wrong 3-phase 3-wire or 3-phase 4-wire setting, or improper phase sequence. Check the wiring diagram, CT direction and meter configuration before commissioning. Installation and troubleshooting should be completed by qualified electrical personnel.
