Landis+Gyr E880

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… Read more
