AI Technical Summary
Technical Problem
Determining the cause of electrical power grid failures in diverse environments is challenging, especially in underground networks, where sensor systems struggle to accurately detect and locate partial discharge events.
Method used
A power-line-monitoring system with capacitive coupling to the shield layer of a cable, incorporating high-pass filters and processing circuitry to detect partial discharge events, and inject identifiers to communicate the event location, using retrofittable devices that minimize cable modification.
Benefits of technology
Enables precise detection and localization of partial discharge events, facilitating proactive maintenance and reducing cable damage, while supporting various monitoring functionalities for grid operators.
