描述了一种新型保护继电器，它解决了与超高压和未来特高压系统保护相关的许多问题。基于行波方法，继电器系统以超高速运行，可以在几毫秒内检测并确定故障方向。介绍了继电器的工作原理、设计和应用，以及计算机模拟研究和实验室测试的结果。第一个继电器系统安装在美国 Bonneville 电力管理局的 500 kV 系统中，对目前缩短故障清除时间作为提高系统稳定性和电力传输能力的方法做出了重大贡献。
A new protective relay that solves many of the problems associated with the protection of EHV and future UHV systems is described. Based on a traveling wave approach the relay system operates at ultra high speed and can detect and determine the direction to a fault in a few milliseconds. The relay operating principle, design and application are presented as well as results from computer simulation studies and laboratory tests. The first relay system was installed in the USA in Bonneville Power Administration's 500 kV system and represents a substantial contribution to present efforts to shorten fault clearing times as a method to improve system stability and power transfer capability.
