Three-phase electricity meter

Multi-tariff, four-quadrant electricity meter

• Measurement of active, reactive and apparent energy
• Direct, semi-direct and indirect connection through current transformers, optionally also through voltage transformers
• Three built-in communication ports: one optical, two serial
• Provides full compatibility with smart systems

Application

Multi-tariff, four-quadrant electricity meter in three-phase, three- or four-wire networks for HV-, MV- or LV-powered consumers of all tariff groups. Extended measuring and registering functionality is complemented by multiple communication options. It is an optimal solution for advanced power management systems (EMS). Typical use: commercial/industrial meter; balancing meter.

Features

• Measurement of active, reactive and apparent energy
• Measurement of instantaneous, maximum, redundant and cumulative power
• Measurement of transformer losses: OLA, NLA, OLR, NLR, I²t, U²t
• Measurement of network parameters, including: voltages, currents, voltage and current harmonics, frequencies, THD, assymetry factor and neutral wire current
• Monitoring of power grid parameters: voltage dips and swells; long power outages; current and voltage asymmetry; current flow with no applied voltage; no current flow; exceeded current limit
• Direct, semi-direct and indirect connection through current transformers, optionally also through voltage transformers
• Recording of energy in six tariff zones, switched by a built-in real time clock
• Wide range of recording capabilities for measured parameters:
  • independently configurable profiles with different recording intervals
  • ability to configure a different set of recorded data for each profile
• Enhanced event logging
  • 7 groups of events, recorded in independent logs
  • sending immediate event notifications to the host device/system
• Wide range of recording capabilities for measured parameters in reference periods
  • up to 50 parameters recorded in reference periods
• DLMS/COSEM communication protocol, possibility to read measurement data through the PN-EN 62056-21 (IEC1107) protocol
• Three built-in communication ports: one optical, two serial
• Interchangeable communication module: 3G/GPRS or Ethernet
• Built-in emergency power supply connected to an external power source
• Ability to read energy registers on the display in case of power outage – powered by a replaceable AA battery.
• Ability to read profiles and reference periods on the LCD
