SETS-13 Three-Phase Electricity Meter

SETS-13 Static Direct Connected Three-Phase Electricity Meter is designed to measure active electric power consumption in three-phase four-wire mains (3×230/400 V, 50 (60) Hz) in the premises protected from corrosive gases and vapour. Readings of the meter conform to the power consumed by the monitored mains.

The counting device of the electricity meter has 6 digits and gives readings in kWh, at that, the rightmost (lesser) digit indicates deciles of kWh.
