Landis+Gyr E880

Description:

Metering innovation for digital substations with non-conventional instrument transformers

The E880 is a high-precision electricity meter designed for transmission networks and digital high-voltage substations with non-conventional instrument transformers (NCIT) according to IEC 61850 standard. The meter uses digital sample values of phase voltages and phase currents as per IEC 61850-9-2 LE for billing and diagnostics. The merging unit’s current and voltage outputs enter the E880 grid meter as a single data stream. The input for sampled values is adaptable to every substation environment either using optical fiber (100 base FX) or Ethernet with RJ45 (10 base TX), and covers different customer needs. E880 delivers operational efficiency thanks to its full compatibility with the customer’s existing meter reading system and a comprehensive, future-proof functionality set, including modular multi-channel communication platform.

Based on the proven E850 technology, the E880 grid meter offers top accuracy and long-term stability in energy measurement under all operating conditions. The highest metering accuracy generates savings for the customers and the precision is guaranteed even at the lowest load of 2% in a single-phase operation, unbalanced or cos φ below 1. The E880 powerful measurement system provides sufficient resolution for measurement periods under 15 minutes (1 to 5 minutes), accurate metering when energy direction changes and very low sensitivity to temperature changes.

Easy to handle rack mount design enables energy companies to save installation costs and space.

The E880 grid meter is available in one main version:

• E880 f9 rack mounted with Essailec® connector
