ABB REF615 HCFKAEADABC2DAA11E digital protective relay

Protection function
With a variety of protection algorithms, it can quickly and accurately detect and protect multiple fault types such as over current, under current, over voltage, under voltage, ground fault, differential protection, etc.
With adaptive protection function, it can automatically adjust the protection parameters according to the running state of the power system, improve the reliability and sensitivity of the protection.

Control function
Supports remote and local control of power devices such as circuit breakers and isolation switches. The remote control commands are received through the communication interface to realize the on-off operation of the device, and the local operation interface is also provided to facilitate the operation of field maintenance personnel.
With synchronous detection and automatic quasi-synchronous function, it can ensure the safe and reliable operation when the power system is juxtaposed or unaligned, and avoid the impact of non-synchronous switching on the system.

Measuring function
It can accurately measure various kinds of electricity in the power system, such as voltage, current, active power, reactive power, power factor, frequency, etc. The measurement accuracy is high, which can meet the requirements of power system for measurement and monitoring.
The harmonic analysis function can monitor and analyze the harmonic content in the power system in real time, help users find harmonic problems in time, take corresponding measures to ensure the power quality of the power system.

Monitoring function
Real-time monitoring of power equipment and power system operating status, including equipment temperature, humidity, pressure and other environmental parameters as well as equipment running time, operation times and other information. Through the analysis of these data, the potential faults of the equipment can be discovered in advance, and the maintenance cost can be reduced.
With event recording and fault recording function, it can record various events in the power system, such as protection action, switch change, abnormal signal, etc., and record the fault process in detail, providing a strong basis for fault analysis and accident handling.

Communication capability
REF615 supports a variety of communication protocols, such as IEC 61850, Modbus, DNP3, etc., and can easily communicate with substation automation systems, dispatch centers, and other intelligent devices to achieve information sharing and interaction.
Through the high-speed Ethernet interface or serial communication interface, the protection, control, measurement and monitoring data can be quickly and stably transmitted to ensure the real-time and reliability of the system.
