Product Details: RED521 1MRK002003-BA ABB Universal Differential Protection Terminal
Differential protection function:
RED521 1MRK002003-BA detects faults by comparing the difference in current entering and leaving the protected area, achieving rapid response and fault isolation. This differential protection mechanism is of great significance in preventing faults such as short circuits and overloads in the power system.
Strong adaptability:
This product is easy to adapt to different substation configurations and has a wide range of self-monitoring functions to ensure stable operation under various working conditions.
Real time and accuracy:
Real time clock is synchronized with external devices to ensure the accuracy of timestamps. Differential protection and operation time usually only take 10-15 milliseconds, which improves the real-time and accuracy of the protection.
Low CT requirements:
RED521 1MRK002003-BA has lower requirements for CT (current transformer), and can operate correctly with only 2 milliseconds of saturation, reducing the requirements for CT performance.
Multiple measurement areas and CT inputs:
A three-phase terminal with a measurement area provides busbar protection for up to six partitions in a single area. Three single-phase terminals with two measurement zones provide phase separated bus protection for up to 18 CT inputs.
Monitoring and Communication:
Provide an event list function that can record up to 16 events and display simulated service values for each stage and protected area. Supports serial data communication, facilitating data exchange and monitoring with upper level systems.
User friendly interface:
Built in local human-machine interface and LED indicator, convenient for users to view and operate status
