THREE-PHASE ELECTRIC ENERGY METER SEA3.
Purpose
Accounting of electric energy on single-tariff in three phase three- or four-wire AC chains directly or through measuring current transformers, stand-alone or with informing-measuring systems as an energy gain and power measuring units. Three-phase, static, electronic electric energy meters SEA33 are electro technical devices constitutes itself analogue-digital units realizing summing up and indication on lector-mechanical counting device or electronic display the quantity of consumed power directly in kWt/h.
Application field
In consumer and industrial sector in electric energy consumption in three-phase electric chain (industrial companies, residual and public buildings, portable constructions, cottages, country houses, garages etc.)
