Cable failures are among the most costly and unpredictable events in power networks. This session shows how frequency-domain reflectometry diagnostics detect early degradation, joint issues, and hidden defects across the full cable length, on both energized and de-energized assets. Attendees will learn how asset owners use LIRA technology to reduce unplanned outages, extend cable lifetime, lower maintenance spend, and strengthen documentation for aging infrastructure. Real-world examples from utilities, offshore wind, and industrial operators show how continuous cable health intelligence turns reactive repairs into planned, data-driven decisions.
