Multifunctional Three-Phase Electric Energy Meters NEVA ST4 for Accurate Energy Measurement

Meters of transformer or direct inclusion are designed for measuring and accounting of active (in 2 directions) and reactive (inductive and capacitive in each of 4 quadrants) energy in three-phase three- or four-wire AC circuits, measuring current in the neutral wire. They perform multi-tariff electricity metering, with the possibility of application as part of the AIMC and support of the SPODES protocol. Provide the necessary functionality in accordance with PP No.
