9521052 Olsen In recent years, the design and use of compact transmission lines has become more common for reasons related to aesthetics, power transmission efficiency and environmental concerns. Hardware on these compact lines is exposed to higher surface electric fields than on lines of more conventional designs. Thus, corona which is responsible for a number of undesirable effects, is a more important design criterion for hardware to be used on new and upgraded lines. In this work, it is proposed to develop a new methodology for the design of such hardware. The first part is to develop an appropriate criterion for predicting the initiation of corona streamers on conductors with curvature in two directions. To do this, a theory described in this proposal will be calibrated using a set of carefully controlled corona initiation experiments. The second is to incorporate this theory as an optimization criterion in a computer program to design hardware. Finally, a number of hardware designs will be developed and tested against those developed with simpler existing criteria. ***

小行星9521052 近年来，出于与美学、电力传输效率和环境问题相关的原因，紧凑型传输线的设计和使用变得更加普遍。 这些紧凑型线路上的硬件比更传统设计的线路暴露于更高的表面电场。 因此，电晕是造成许多不良影响的原因，是新线路和升级线路上使用的硬件的更重要的设计标准。 在这项工作中，建议开发一种新的方法来设计这样的硬件。 第一部分是发展一个适当的标准预测电晕流光的起始导体上的曲率在两个方向。 为了做到这一点，本提案中描述的理论将使用一组仔细控制的电晕引发实验进行校准。 第二种方法是将这一理论作为优化标准纳入计算机程序中，以设计硬件。 最后，将开发一些硬件设计，并与那些用更简单的现有标准开发的硬件设计进行测试。 ***
