Analysis of the Anti High‐Altitude Electromagnetic Pulse Interference Ability of Relay Protection Devices

High Voltage, EarlyView.
ABSTRACT High altitude electromagnetic pulse (HEMP), as a steep slope and high amplitude instantaneous energy shock, has stronger coupling and greater destructive power, which can easily cause the secondary control device of the substation to malfunction.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

Journal of Synchrotron Radiation, EarlyView.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact
