保护功能还支持不同类型的网络，例如隔离中性网络、谐振接地网络和部分接地网络。应用领域还包括中型三相异步电动机以及用于无功功率补偿的并联电容器组的保护和控制。除了保护、测量、控制、状态监测和一般功能外，REF545馈线终端还配备了大量PLC功能，可将变电站自动化所需的多种自动化和顺字透辑功能集成到一个单元中。
这款装置能够感应电力系统中的异常电流、电压信号并与事先设定的故障保护条件进行比较。一旦检测到故障，它会迅速切断故障环节，防止故障向整个电网扩散。这有助于减少故障对电力系统的影响，保障电力供应的连续性和稳定性。
The protection function also supports different types of networks, such as isolated neutral networks, resonant grounded networks, and partially grounded networks. Applications also include protection and control of medium-sized three-phase asynchronous motors and shunt capacitor banks for reactive power compensation. In addition to protection, measurement, control, condition monitoring and general functions, the REF545 feeder terminal is equipped with a large number of PLC functions to integrate a variety of automation and sequential transmission functions required for substation automation into a single unit.
The device can sense abnormal current and voltage signals in the power system and compare them with pre-set fail-safe conditions. Once a fault is detected, it quickly cuts off the fault link and prevents the fault from spreading throughout the grid. This helps to reduce the impact of faults on the power system and ensure the continuity and stability of the power supply.
