Phasor Measurement Units

Phasor Measurement Units (PMUs) are devices used in electrical power systems to monitor the flow of electricity in real time. They measure the electrical waves' phase angle and magnitude, providing valuable data on the grid's performance. This information helps engineers detect and manage issues like power imbalances or outages, ensuring a stable and reliable supply of electricity. By using PMUs, utility companies can better understand the dynamics of the power grid and respond quickly to potential problems, ultimately enhancing the overall efficiency and security of electricity delivery.
