The REX521GHHPSH51G feeder protection relay is a device that plays an important role in the power system. Its main function is to quickly cut off faults in the event of short circuits, grounding faults, or other abnormal situations in the feeder line, thereby protecting the stable operation of the power system. It can sense abnormal current and voltage signals in the power system and compare them with pre-set fault protection conditions. Once a fault is detected, it quickly cuts off to prevent the fault from spreading to the grid.

Specifically, the relay has multiple protection functions such as overcurrent protection, short circuit protection, and ground fault protection. When overcurrent or short circuit occurs, the relay will promptly cut off the circuit to prevent dangerous situations such as equipment damage or fire. At the same time, for power systems with neutral grounding, it can also detect grounding faults and take appropriate protective measures.

In addition, the REX521GHHPSH51G feeder protection relay also has some other characteristics and advantages. For example, it supports redundant power inputs, increasing the reliability of communication networks; Provide management functions that can be managed through web browsers, CLI, and SNMP; Simultaneously supporting multiple interface configurations, flexible optoelectronic combinations can be made according to business interface requirements; It also has an industrial grade design that can work stably within the working temperature range of -40~85 ℃, meeting the requirements of various industrial sites.

Overall, the REX521GHHPSH51G feeder protection relay is a device with comprehensive functions, stable performance, and easy operation, which can provide strong guarantees for the safe and stable operation of the power system.
