PMU technology

Phasor Measurement Units (PMUs) are advanced devices used in electrical power systems to monitor real-time conditions. They measure the electrical waves—specifically voltage and current—with high precision and synchronize these measurements across different locations using GPS signals. This synchronization allows grid operators to get a precise snapshot of the power system’s state, helping detect and respond to issues quickly. PMUs improve the stability and reliability of the electrical grid by providing valuable data for grid management, fault detection, and system optimization, ultimately enhancing the safety and efficiency of power delivery.
