Three-Phase Electronic Energy Meter

Three-phase electronic energy meters are used wherever the load is large: factories, workshops, commercial buildings, telecom sites and utility distribution. We produce them in our own factory in Wenzhou, China and test every unit before shipment.

What Is a Three-Phase Electronic Energy Meter?

It is a static meter that measures three live wires (three-phase three-wire) or three live wires plus neutral (three-phase four-wire). Because there are no moving parts, it keeps its accuracy over years of continuous operation and can carry communication and multi-tariff functions.

Variants We Produce

• Direct-connected meter — the load current passes through the meter directly, for smaller industrial and commercial supplies.
• Transformer-operated meter — connected through current transformers for large loads.
• Multi-tariff meter — separate registers for peak, flat and valley periods.
• DIN-rail 4P meter — compact modular meter for panel and distribution-board metering.
• High-power meter — for heavy loads up to 250A.
• Communication meter — RS485 with Modbus-RTU or DL/T645-2007 for remote reading.
