3-Phase Meter with different modem (PLC/RF/GSM/TCP/IP/RS485/M-Bus) and load connection / disconnection relay.
Meters are intended for individual work with three-phase end-consumers in 0.4 kV power network environment. Meters with complete set of functions have the following possibilities:
Automatic multi-tariff metering of consumed active and reactive electrical energy.
Provide possibility of remote data collecting, by means of built-in PLC-modem of a subsidiary communication channel.
Allow remote consumption control, or power supply of separate load by means of built-in breaking relays: main or subsidiary.
Control differential current, or measure consumption of energy, correlated with the differential current.
Meters can support both prepayment and credit operation modes. At operating in prepayment mode there is not required installation in meter of special cards all the necessary information about payment for energy meter receives via communication channels.
Meters accumulate, save and transmit to Center information about:
alarm situations in network;
their own alarm states;
consumers actions, which can lead to breach of contract with electrical energy supplier.
Meters meet the requirements of the following international standards:
IEC 61010-1:2001-02 Safety requirements for electrical equipment for measurement, control and laboratory use. Part 1. General requirements
IEC 62053-22:2003 Electricity metering equipment (a.c.) - Particular Requirements - Part 22: Static meters for active energy (classes 0,2 S and 0,5 S)
