A synchrophasor is a type of measurement used in the power grid to provide real-time data about the electrical network. Synchrophasors are used to monitor the performance and stability of the power grid, and they can be used to detect and diagnose problems in the system. Synchrophasors are typically measured at 60 times per second, and they provide accurate, high-resolution data about the voltage, current, and frequency of the electrical signals in the grid. This information can be used to optimize the operation of the power grid and to improve its reliability and stability.
The deployment of synchrophasors varies among different utilities and countries. In some cases, synchrophasors may be deployed across the entire power grid of a utility, while in other cases they may be deployed only in certain parts of the grid or in certain types of equipment. The decision to deploy synchrophasors is typically based on the needs and priorities of the utility, and the specific characteristics of the electrical network.

In general, synchrophasors are most commonly used in transmission systems, where they can provide valuable information about the performance and stability of the grid. They may also be used in distribution systems, especially in areas with high levels of renewable energy generation or in systems with complex load patterns. Some utilities may also use synchrophasors in their generation facilities to monitor the performance of their power plants.
