LF Energy Summit Europe 2026

Transmission substations are expected to host more monitoring functions, but each one adds hardware, wiring, panel space, engineering effort and lifecycle cost. In EcoPhi’s 400/225 kV digital substation project with RTE, the approach is one measurement layer supporting multiple virtualized applications.

EcoPhi’s QMU 800 acts as the digital measurement layer, sampling voltage and current signals at up to 2 MHz. The setup follows IEC 61869, allowing substation signals to be digitized once and reused by software applications. EcoPhi’s CMPC 800 provides the edge platform where applications run in a virtualized environment using SEAPATH.

This enables PQ monitoring, PMU/synchrophasor functions, PD monitoring, digital fault recording and digital fault location to run as virtualized applications instead of separate devices. By decoupling measurement from applications, the system reduces hardware duplication, panel complexity, copper wiring, installation, commissioning, maintenance and lifecycle cost.

The presentation will describe the RTE architecture, IEC 61869 setup, roles of QMU 800 and CMPC 800, and lessons from preparing a transmission-grade virtualized substation.
