Synchrophasor

A synchrophasor is a device used in power grids to measure and monitor the voltage and current at different locations simultaneously with high precision and synchronized timing. Using GPS clocks, these devices provide real-time data on the electrical waves, enabling operators to analyze the stability and flow of electricity across the network. This helps in quickly detecting problems, preventing blackouts, and improving the reliability of power systems. Essentially, synchrophasors offer a detailed, real-time "snapshot" of the grid's condition, enhancing its safety and efficiency.
