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).
