ARIS EM DIGITAL MULTIFUNCTION ELECTRIC ENERGY METER WITH IEC 61850-9-2LE INTERFACE

ARIS EM electric energy meter is designed for measurement and multi-tariff active and reactive power metering, load power profile arrays generation and management with configurable integration time (considering power losses), power maximums determination, power quality parameters measurement and calculation with data acquisition according to IEC 61850-9-2LE protocol. ARIS EM can be used as a part of digital substation revenue metering system.

Key Function:

  • Reception of up to 4 IEC 61850-9-2LE streams (80 or 256 samples/cycle)
  • Multi-tariff active and reactive electrical energy metering (direct/reverse) and four-quadrant reactive energy metering
  • Tariff-free energy metering, taking into account active and reactive power losses in electric power lines and in power transformers
  • Active energy metering accuracy class – 0.2S; reactive energy metering accuracy class – 0.5
  • Measurement and calculation of more than 80 secondary electrical parameters of three-phase four-wire network
  • Generation and management of 3 independent load profile arrays (energy, power) with different averaging intervals (1 – 60 minutes) with storage duration of up to 150 days
  • Billing: 8 tariffs, 12 seasons and 8 types of days
  • Electrical parameters calculation according to EN 50160:2010 standard
  • Alarm signaling and self-supervision
  • Integrated real-time clock
  • Time synchronization from NTP, PPS, PTP clocks
  • Time-stamping with 1 ms time resolution
  • Event logs generation and display
