Time–frequency characteristics and influencing factors of the pressure wave caused by power–frequency arc inside a closed oil tank

High Voltage, Volume 10, Issue 3, Page 699-709, June 2025.
Abstract The arc faults inside oil‐immersed power equipment can produce high‐amplitude pressure waves inside tanks, which might cause ignition and explosion accidents. This kind of failure is one of the most severe faults for power equipment and has attracted considerable attention in recent years.

The relationship between power of arc discharge in transformer oil and peak value of the shock wave

High Voltage, Volume 10, Issue 1, Page 157-166, February 2025.
Abstract Since 2018, there have been seven incidents of explosions and fires in ultra‐high voltage transformers in China, which are caused by internal arc discharge in transformer oil. Various pressure measurement experiments have been conducted to explore the laws of discharge pressure. However, differences in experimental conditions, discharge energy,
