摘　　要：跨电压等级同塔线路的互感是继电保护整定计算面临的新问题。为此,介绍了跨电压等级同塔线路的互感参数的测试新方法和实测例子。通过获取的互感实测参数从定量上分析了其对继电保护整定计算的影响,并提出了在继电保护设备选型和整定计算中应注意的问题。Mutual inductance between multiple-circuit lines of different voltage grades is a new problem to setting calculation of relay protection. In this paper, a new measuring way of the said mutual inductance and its example are presented. Based on quantitative calculation analysis of the example, its influence on setting calculation of relay protection is discussed. Some points for attention in setting calculation of relay protection and in choosing types of relay devices are also set forth.
