Sensing and measurement technologies collect data to evaluate and monitor the state operation and equipment health status which support the grid's functionality and higher reliability. Also, this serves customers in improving their electrical usage by giving them information regarding their daily demands. Sensing and measurement technologies include sensors, phasor measurement units, and advanced metering infrastructures (AMI). All this supports a wide‐area monitoring system, time‐of‐use, assets functionality, real‐time pricing, and the system proper operation. A phasor measurement unit is a high‐speed sensor integrated with the power grid to monitor power quality by allowing data to be obtained at certain instants of time. Phasor measurement units can be considered as a health‐meter of the grid as they collect different measurements of voltage, phase, and current to be analyzed. This will help to reduce blackouts and provide a wide‐area situational awareness.
