Beyond 60 Hz: Wideband Sensing for Grid Dynamics and Resilience

The evolving electric grid faces challenges from extreme weather events, high renewable penetration, inverter-based resources, and power electronics, which introduce fast transients and harmonics beyond the reach of conventional 60/50 Hz instrument transformers. These dynamic phenomena impact system stability, protection, and asset health, yet remain largely invisible with traditional measurement approaches. Wideband optical voltage and electric field sensing technologies offer a non-intrusive, quick- to-deploy, and effective way to capture events from fundamental frequency up to the MHz range. By improving visibility into grid dynamics, these sensors (and the associated software applications using their deep data) enable accurate fault location, power quality monitoring, and situational awareness during disturbances. Their scalability and ease of deployment make them valuable for enhancing operational efficiency, supporting predictive maintenance, and informing planning for future grid modernization and hardening. This presentation explores the role of wideband sensing in strengthening grid resiliency and reliability.
