High Voltage, EarlyView.ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

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.

Embolic Agent Selection and Outcomes in Renal Angiomyolipoma Embolisation
Journal of Medical Imaging and Radiation Oncology, EarlyView.ABSTRACT Purpose To evaluate whether embolic agent selection influences outcomes following selective arterial embolisation (SAE) of renal angiomyolipomas (r‐AMLs) and to assess procedural safety and effects on renal function. Materials and Methods A retrospective observational study was performed of all r‐AML SAEs undertaken at a tertiary institution ...
