Market Definition
A merging unit (MU) is a smart electronic unit applied in digital substations to transform analog signals of current transformers (CTs) and voltage transformers (VTs) to digital Sampled Values (SVs) in accordance with IEC 61850 standards. It measures and transmits these measurements to protection relays, control systems, and monitoring equipment using fiber-optic communication, which is digitized, time synchronized, and sent to the relays. A merging unit allows better precision, less installation complexity, and higher dependability of substations by substituting the traditional copper wiring with digital streams of data. It serves as a key interface between primary equipment and secondary systems, allowing the entirely automated, adaptable, and interoperable operations of a grid in a contemporary power network.
