Merging units are a key element of the process bus concept, enabling the digitization of analogue, binary and command information into the IEC 61850 format so that end-to-end digitization can be achieved, contributing to a full digital substation.
Networked Merging Units
The MU320E is a Process Interface Unit (PIU) with analog and binary interfaces enabling digitization using the IEC 61850 standard. It provides GOOSE status messages from the breaker and digital Sampled Values (SV) from CTs and VTs. It also enables full switchgear control using GOOSE commands and High Speed High Break circuits.
Multilin HardFiber System
A Process Bus Solution that allows the mapping of measurements made in the switchyard to protection relays located in the control house using IEC 61850 communication over fiber optic cables.
