Restrike characteristics of vacuum circuit breaker in its opening process under DC voltage
IET Science, Measurement & Technology, 2023 The restrike of vacuum circuit breaker during the breaking process causes overvoltage and intensifies the insulation deterioration of high‐voltage equipment. To solve this problem, the vacuum breaker aging test method and the restrike characteristics are

Space Weather, Volume 24, Issue 9, September 2026.Abstract Space weather risk assessment is constrained by the lack of available asset information needed to model geomagnetically induced currents (GICs) in electricity transmission infrastructure. We propose a systematic method that enables risk analysts to collect their own open‐source substation data.
