GST7666-G Three Phase Smart Electricity Meter

The G meter is a cost-effective solution for smart metering, data reading and load balance operations. The meter goes with four-wire direct connection type, 100 Amp per phase in a compact BS housing. CT(Current Transformer) connection type with 1. 5(6)Amp per phase is also available on request. It is ideal for large residential homes, small commercial and industrial applications

The meter is manufactured by Iso9001 standards and IP54 protection rating. It offers two way communication by DLMS/COSEM protocol via modular Ethernet/GPRS/PLC/RF com port and allows dynamic AMI interactions and reliable metrological operations at the same time
