High Voltage, EarlyView.ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.

Failure Probability Evaluation of GIL Tri‐Post Insulators Under Electromechanical Stresses
High Voltage, EarlyView.ABSTRACT Based on the energy theory, this paper proposes an evaluation method for the breakdown failure probability of the tri‐post insulator in a gas‐insulated metal‐enclosed transmission line (GIL). Various internal defects, vector forces and torque forces were considered, along with the application of an AC voltage.

Shock accelerated cylindrical gas inhomogeneities. Part 2 - A heavy gas cylinder [PDF]
, 1993 Experiments have been carried out in which a cylindrical volume of a heavy gas is impulsively accelerated by a weak shock wave. A laminar jet of sulphur hexafluoride (SF_6) is used to produce the heavy gas cylinder.

High Voltage, EarlyView.ABSTRACT The breakdown characteristics of the novel eco‐friendly insulating gas CF3SO2F are fundamental to the design of gas‐insulated equipment. In this paper, the gas mixture parameters for CF3SO2F were optimised for different ambient temperatures in order to ascertain the insulation performance and liquefaction temperature constraints.

气体分解产物和局部放电测试技术在SF6电气设备状态诊断中的应用
Gaoya dianqi, 2014 主要介绍了SF6气体分解产物、局部放电测试这2种检测技术在SF6电气设备状态诊断中的几起成功应用的案例。这些案例各有特点:SF6气体分解产物异常但不存在局部放电信号;SF6气体分解产物正常但存在局部放电信号;SF6气体分解产物异常且存在局部放电信号;SF6气体分解产物异常但无法采用局部放电测试技术进行检测。通过解体,均验证了设备存在缺陷。因此,SF6气体分解产物、局部放电测试技术在SF6电气设备潜伏性故障诊断方面具有广阔的应用前景。
