方向过电流继电器（67）是指可以使用电压和电流的相位关系来确定故障方向的继电器。有各种各样的概念来完成这项任务。本文综述了继电保护67种方向判断的主流方法。本文重点讨论了数字方向继电器如何使用序分量的相位关系，如正序（V<sub>1</sub> vs. I<sub>1</sub>）、负序（V<sub>2</sub> vs. I<sub>2</sub>）和零序（V<sub>0</sub> vs. I<sub>0</sub>）来感测故障方向，但其他概念，如使用正交电压（例如，V<sub>AB</sub> vs I<sub>c</sub>）包括在内
Directional overcurrent relaying (67) refers to relaying that can use the phase relationship of voltage and current to determine direction to a fault. There are a variety of concepts by which this task is done. This paper will review the mainstream methods by which 67 type directional decisions are made by protective relays. The paper focuses on how a numeric directional relay uses the phase relationship of sequence components such as positive sequence (V<sub>1</sub> vs. I<sub>1 </sub>), negative sequence (V<sub>2</sub> vs. I<sub>2</sub>), and zero sequence (V<sub>0</sub> vs. I<sub>0</sub>) to sense fault direction, but other concepts such as using quadrature voltage (e.g., V<sub>AB</sub> vs I<sub>c</sub>) are included
