Phasor Measurement Units (PMUs)

Phasor Measurement Units (PMUs) are advanced devices used in electrical power systems to measure the voltage and current at specific points with high accuracy and real-time data. They capture the magnitude and phase angle of electrical waves, allowing operators to monitor the stability and performance of the power grid more precisely. By synchronizing measurements across locations using GPS signals, PMUs enable a detailed, real-time view of how the grid behaves, helping prevent outages and improve reliability. Essentially, they provide critical insights into the dynamic conditions of electricity flow for better grid management.
