Characterising power quality disturbances resulting from current limiting fuse operation
Ingeniería e Investigación, 2011 This article presents novel and easily implemented tools for characterising electrical disturbances originated by fuse operations. A methodology is described that (with the use of some descriptors) led to identifying electrical disturbances of this kind.

Dianci bileiqi, 2019 配电变压器绝缘水平较低,易遭受雷电侵害,其安全性对配电系统稳定可靠运行具有十分重要的意义。基于散射参数测量法,测量并进行数据处理获得配变的阻抗幅频特性,根据谐振理论构建了宽频数学模型并引入数学算法对模型参数进行优化。通过调研某地区10kV配电线路实际运行中配电变压器的雷击损坏情况,发现了配电变压器中性点绝缘较为薄弱,现有雷电防护措施不能对其进行有效的保护这一问题。利用已建模型,通过在ATP-EMTP中对这一问题进行理论分析与仿真计算,提出了在配电变压器高压侧中性点加装避雷器 ...
