【 ABB RET650 1MRK006516-AD  】

ABB RET650 is a feature rich protective relay suitable for applications such as protection, control, and monitoring in power systems. It belongs to ABB’s power protection and control system product series, widely used in the protection and control systems of high-voltage transmission lines and substations. The RET650 device is designed to provide fast and selective protection, suitable for dual winding, triple winding transformers, autotransformers, generator transformer units, and shunt reactors.

parameter
RET650 supports multiple input voltage ranges, including AC 100-240V or DC 48-250V, with a frequency range of 50/60 Hz. The protection level is IP40 (front panel) and IP30 (back panel). In addition, RET650 provides multiple communication interfaces, supporting protocols such as IEC 61850, Modbus RTU/TCP, DNP3.0, SPA, and has Ethernet and serial interfaces. The working temperature range is -40 ° C to+70 ° C, and the weight is approximately 3kg.

application area
RET650 is mainly used for transformer protection in power systems, including protection, monitoring, and control of double winding and three winding transformers, autotransformers, generator transformer units, and splitters. It is also applicable to the protection and control systems of high-voltage transmission lines and substations. The flexibility of RET650 makes it an ideal choice for new construction and retrofit installations.

advantage
Comprehensive protection function: RET650 provides overcurrent, undervoltage, overvoltage, and frequency protection, as well as differential protection for transformers and generators.
Flexible logic configuration: The device provides a flexible logic engine that allows users to create custom protection schemes and control logic.
Rich communication interfaces: Supports multiple communication protocols, facilitates integration with other devices and systems, and enables centralized monitoring and management of the power system.
High sensitivity and fast response: RET650 has a highly sensitive differential protection function, which can quickly detect and respond to internal faults, preventing serious damage.
Low requirement CT configuration: RET650 has lower requirements for the main current transformers (CTs) and does not require CT insertion, simplifying the installation and configuration process.

ABB RET650 1MRK006516-AD is a powerful and flexible protective relay suitable for various power system applications, providing comprehensive protection and efficient system management.
