Description

ABB REL561 1MRK002496-AC Feeder protection relay

It is a digital, multifunctional protection relay designed for medium voltage power grids, mainly used for protection, control, measurement and monitoring of distribution feeders.

 

1. Comprehensive Protection Functions:

   • Overcurrent Protection: Provides directional or non-directional instantaneous, definite time, and inverse time overcurrent protection, which is the core of feeder protection.

   • Auto-reclosing: Built-in auto-reclosing function to quickly restore power after transient faults (e.g., lightning strikes, wind-blown debris), improving power supply reliability.

   • Earth-Fault Protection: Offers sensitive directional and non-directional earth-fault protection, suitable for different grounding systems (solidly grounded, resistance grounded, ungrounded or compensated).

   • Thermal Overload Protection: Protects cables and transformers from thermal damage.

   • Voltage Protection: Includes overvoltage and undervoltage protection.

   • Frequency Protection: Includes overfrequency and underfrequency protection.

   • Breaker Failure Protection: Initiates backup tripping if the circuit breaker fails to trip.

2. Control and Monitoring:

   • Local and Remote Control: Supports control of circuit breakers, disconnectors, etc., via the front panel or a remote SCADA system.

   • Measurement and Metering: Real-time measurement and display of electrical parameters such as current, voltage, power, power factor, frequency, and energy.

   • Event Recording: Records time-tagged (with millisecond accuracy) protection trips and alarms for easy fault analysis.

   • Fault Recorder: Records current and voltage waveforms before, during, and after a fault, serving as a powerful tool for incident analysis.

   • Data Logging: Records trends of measured values for load analysis and equipment condition monitoring.

3. Communication and Integration:

   • Robust Communication Protocols: Supports multiple international standard protocols, such as IEC 61850 (Station and Process Level), IEC 60870-5-103/101, DNP3.0, Modbus®, etc., enabling seamless integration into modern digital substations.

   • Hardware Interfaces: Provides multiple serial communication ports and Ethernet interfaces.

4. Hardware Characteristics:

   • Rugged Design: Designed for harsh industrial environments with high immunity to electromagnetic interference.

   • Modular Design: Features flexible I/O configuration that can be customized according to actual application requirements.

   • User-Friendly Interface: Equipped with a large graphical LCD display and navigation keys for easy local operation and information viewing.
