本文介绍了一种新的相间回路阻抗测量方法。该方法保证了故障回路电抗计算的更高精度。因此，保证了应用于输配电线路保护的距离元件在操作中的更好的选择性和安全性。此外，该方法还实现了故障电阻与负荷状态的分离。由于这一事实，不需要针对负载侵入的特殊措施。它有助于简化距离保护设置。
In this paper a novel impedance determination method for the phase-to-phase loops is described. This approach promises a better accuracy of the reactance calculation of the faulty loops. Thus, better selectivity and security in operation of the distance element applied for the protection of transmission and distribution lines is guaranteed. Moreover, with this new method the separation of the fault resistance from load condition is achieved. Due to this fact, special measures for load encroachment are not necessary. It contributes to simplification of distance protection settings.
