REX 521 饋線和電動(dòng)機(jī)保護(hù)繼電器設(shè)計(jì)用于在中壓電力系統(tǒng)中進(jìn)行保護(hù)、控制、測(cè)量和監(jiān)控。典型的應(yīng)用包括進(jìn)、出饋線以及變電站保護(hù)、保護(hù)繼電器配有用于常規(guī)電流和電壓互感器的交流量輸入端。此外，該繼電器還提供含電流和電壓傳感器輸入的硬件版本該繼電器基于多處理器環(huán)境 HMI 包括一個(gè) LCD( 液晶顯示器 ) 具有不同的視圖，便于本地使用，并通過指示信息通知用戶。在硬件和軟件解決方案中采用現(xiàn)代技術(shù)。

REX 521 是用于配電自動(dòng)控制中變電站自動(dòng)控制概念的一部分，進(jìn)一步擴(kuò)展了系統(tǒng)的功能和靈活性。

The REX 521 feeder and motor protection relay is designed for protection, control, measurement, and monitoring in medium voltage power systems. Typical applications include incoming and outgoing feeders, substation protection, and protection relays equipped with AC input terminals for conventional current and voltage transformers. In addition, the relay also provides a hardware version with current and voltage sensor inputs. The relay is based on a multiprocessor environment HMI, including an LCD (liquid crystal display) with different views for local use, and notifies users through indicator information. Adopting modern technology in hardware and software solutions.

REX 521 is a part of the concept of substation automatic control used in distribution automatic control, further expanding the functionality and flexibility of the system.
