G3G

Transformer connection electricity meter G3G is recommended for operations in transformer substations, because meter measures not only active [kWh], reactive [kvarh] and apparent [kVAh] energies in both consumption and generation directions, but also stores the measurement data profiles (accounting, load and voltage profiles, event logs) and registers the qualitative electrical energy indicators. Voltage fluctuations, voltage harmonic distortion coefficient (THD), three-phase network disbalance and voltage flicker are registered in accordance with EN 61000-4-30 for Class B equipment. In addition, the meter estimates electricity losses both on the transmission line (I2t measurements) and in the power transformer (U2t measurements). Electricity meter interfaces (Ethernet, RS485, optical) support DLMS / COSEM communication protocol, therefore the G3G meter is compatible with equipment of other manufacturers and can work in the automated meter reading systems operating on TCP / IPv4 and HDLC communication networks. The meter is capable of communicating in encryption and authentication mode (AES-128, GCM), which ensures secure data exchange in a common system.
