应用电流差动保护比较进入和离开受保护的架空线路或电缆的电流。需要一个可靠的通信设施，以便在线路末端的终端之间进行信息交换。该差动功能为输电、输电和配电网络提供分相真电流差动保护。它在所有方面都是一个数字系统，用于现代数字通信系统，包括多路复用和路由交换系统。电流在每相的基础上进行比较，避免了电流求和方法的问题，并为单极跳闸提供了相位选择信息。
ApplicationCurrent differential protection compares thecurrents entering and leaving a protectedoverhead line or cable. A dependable communication facility is needed to allow information exchange between the terminals at theline ends.This differential function offers phase-segregated true current differential protection fortransmission, sub-transmission and distribution networks. It is in all a numerical systemfor use with modern digital communicationsystems including multiplexed and routeswitched systems. Currents are compared ona per phase basis, obviating the problem ofthe current summation approach and providing phase selection information for singlepole tripping.
