A Study on the Space Charge Characteristics of AC Sliced XLPE Cables
IEEE Access, 2019 Cross-linked polyethylene (XLPE) cables are widely used in power systems due to their excellent electrical and mechanical properties. Space charge is an important factor in cable aging and breakdown. At present, XLPE cables in the power system are mainly

High Voltage, EarlyView.ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

Design and Deployment of a Regulation‐Compliant Infrared Heating System for UK Field Trials
Plant-Environment Interactions, Volume 7, Issue 5, October 2026.ABSTRACT Free‐air warming systems are essential for simulating climate change in field conditions, yet most are not designed to meet UK or EU health and safety standards. We present the design and field deployment of a hexagonal temperature‐free air controlled enhancement (T‐FACE) system that meets UK and EU health and safety requirements for outdoor ...
