Synchronized phasor measurement unit PMU-101
|
Overview
PMU-101 is a highly accurate synchronized phasor measurement unit (PMU) for wide area monitoring,
control and protection systems, allowing to obtain reliable picture of power grid state in real
time. Global navigation satellite systems (GPS/GLONASS) provide precise synchronization for
phasor time-tagging. Device is IEC 61850 compliant and compatible with other vendors solutions.
