REX521GHHPSH50G comprehensive protection relay

REX521GHHPSH50G is a comprehensive protection relay designed for protection, control, measurement and monitoring

of medium voltage power grids. This protective relay provides the excitation input of conventional current and voltage transformers,

while hardware versions are also available, including input current and voltage sensors.In addition, the REX521GHHPSH50G uses a

multi-processor environment and has HMI (Human Machine interface) features such as navigation buttons, clear/undo

and enter functionslanguage selection, set values password protected, display backlight, display contrast,

display test, selection of primary values, optical isolation serial communication port, and more.

The REX521GHHPSH50G also has some typical applications for protective relays, such as incoming and outgoing feeders

and substation protection. It is also used in modern technology and software to provide protection solutions that further

extend its functionality and flexibility.All in all, the REX521GHHPSH50G is a powerful, high-performance comprehensive

protective relay for monitoring and protection applications in a variety of medium voltage power grids.
