The ABB Transformer Protection RET650 is a smart electronic device (IED) that integrates multiple protection functions to provide protection, monitoring and control for all types of transformers. Here are a few key features of the system:

Multifunctional protection: RET650 can provide differential protection, direction protection, overcurrent protection, overvoltage protection, low voltage protection, frequency protection and other protection functions.

Advanced differential protection: With fast differential protection, it can adapt to the inrush current and avoid false tripping, while having high sensitivity to minor faults in the area.

Human Machine Interface (HMI) : The RET650 features a high-resolution graphic LCD display and buttons for tuning, monitoring, and control.

Communication capability: Supports IEC 61850-8-1 and DNP3.0 communication protocols, and can exchange data with other intelligent terminals and station level systems.

Configuration flexibility: The RET650 offers a variety of pre-defined software packages for different transformer applications, while users can customize the configuration according to their needs.

Self-monitoring and test mode: Self-monitoring and test mode with internal event list simplifies debugging and test process.

Safety features: Comply with the low voltage directive and EMC directive to ensure product safety and electromagnetic compatibility.

The RET650 system is designed to meet the needs of modern substation automation and provide users with an efficient and reliable transformer protection solution.
