REF615E_E is a relay protection device from ABB, and its detailed information is as follows:
Functional Features
REF615E has rich protection functions, including but not limited to overcurrent protection, overvoltage protection, undervoltage protection, differential protection, zero sequence protection, etc. It can accurately detect and quickly respond to various faults in the power system, effectively protecting the safe operation of power equipment.
REF615E measurement and monitoring function: It can measure and monitor various electrical parameters of the power system in real time, such as voltage, current, power, frequency, etc., providing accurate data support for the operation and management of the power system. At the same time, it can also monitor the operating status of the equipment and promptly detect potential faults and hidden dangers.
REF615E has powerful communication functions: it supports multiple communication protocols such as IEC 61850, Modbus, etc., which can easily communicate with substation automation systems or other external devices, achieve information exchange and sharing, and facilitate remote monitoring and management.
REF615E adaptive function: It has adaptive capability and can automatically adjust the protection settings and parameters according to changes in the operation mode of the power system, ensuring that the protection device can maintain good performance under different working conditions.
performance parameter
REF615E rated parameters: The rated voltage is usually 220V or 110V DC, and some models also support AC input. The rated current varies depending on different application scenarios and configurations, generally around 5A or 1A.
REF615E Accuracy: High measurement accuracy, voltage measurement accuracy can reach 0.2% -0.5%, and current measurement accuracy can reach 0.5% -1%. The protection action accuracy can also meet the strict requirements of the power system, ensuring accurate action in the event of a fault.
REF615E action time: Fast protection action time, generally between tens of milliseconds to hundreds of milliseconds, can quickly cut off faults and reduce the impact of faults on the power system.
Application scenarios
Substation: widely used in substations to protect and monitor power equipment such as transformers, busbars, and transmission lines, and is an important component of substation automation systems.
Industrial power system: In the power system of industrial enterprises, it can be used to protect various high and low voltage electrical equipment and ensure reliable power supply for industrial production.
Power transmission and distribution system: suitable for power transmission and distribution networks, protecting transmission lines and distribution lines, and improving the stability and reliability of the power system.
