摘要：
To accurately set an impedance relay it is imperative to know the impedance of the transmission line as well as the earth return path accurately. The electrical impedance parameters of transmission lines are determined either by using suitable software tools or by physically measuring the impedance. Both techniques yield comparable results, if the correct parameters are entered into the software tool.
