英文資料：
The GE SR745-W2-P1-G1-HI-A-L-R-E protection relay is an advanced transformer protection and management relay produced by GE Multilin, specifically designed to provide comprehensive protection, control, and monitoring of transformers. It has a wide range of applications in the power industry, especially in power plants, substations, and industrial facilities. The following is detailed information about this relay:
Main functions and features
Differential protection:
This relay provides high sensitivity differential protection function, which can detect differential current between transformer windings, identify internal faults such as turn to turn short circuits, winding grounding faults, etc.
Overcurrent protection:
Provide multiple overcurrent protection functions, including instantaneous overcurrent, timed overcurrent, and inverse time overcurrent protection, to ensure that the fault circuit is quickly cut off in case of short circuit and other abnormal current situations, protecting the transformer from damage.
Overload protection:
Monitor the load condition of the transformer to prevent long-term overload operation, avoid insulation damage caused by overheating, and shorten equipment life.
Temperature monitoring:
Built in temperature monitoring function, capable of real-time monitoring of transformer windings and oil temperature, providing alarm and trip functions to prevent transformer overheating.
Excitation surge blocking:
By identifying the characteristics of excitation inrush current, it prevents false tripping and ensures the stability of the transformer during operation.
Communication function:
Supports multiple communication protocols (such as Modbus, DNP3, IEC 61850, etc.), can exchange data with other protection devices and control systems, and supports remote monitoring and control.
Event recording and waveform capture:
Equipped with event recording and waveform capture functions, it can record and analyze fault events in the power system, providing data support for fault diagnosis and system optimization.
Automation and Control:
Support automated operations such as automatic reclosing, load switching, and fault isolation to improve system efficiency and reliability.
