  • Overcurrent Protection: Provides both instantaneous and time-delayed overcurrent protection for generators, motors, and transformers.
  • Differential Protection: Protection for transformer and generator windings, including through fault detection and inter-turn faults.
  • Voltage Protection: Monitors voltage levels and provides under-voltage and over-voltage protection.
  • Frequency Protection: Protects against abnormal system frequencies (both under-frequency and over-frequency conditions).
• Communication:
  • Communication Ports: Supports multiple protocols like Modbus, DNP3, IEC 61850 for remote monitoring and control.
  • HMI (Human Machine Interface): Can be connected with remote panels for easy configuration and real-time monitoring.
• Event and Data Logging:
  • Event Logging: Capable of recording events and faults, providing a detailed history of incidents.
  • Data Logging: Continuous logging of system parameters for performance analysis.
• Input/Output (I/O):
  • Configurable digital inputs and outputs for integration with other protection and control systems.
  • Analog inputs for measurement of system parameters like voltage, current, etc.
• Protection Functions:
  • Instantaneous Overcurrent Protection (50)
  • Time-Delayed Overcurrent Protection (51)
  • Under-Voltage Protection (27)
  • Over-Voltage Protection (59)
  • Reverse Power Protection (32)
  • Over-frequency Protection (81O)
  • Under-frequency Protection (81U)
  • Differential Protection (87)
• Relay Control:
  • Allows for remote control of equipment connected to the relay, offering local and remote switching capabilities.
• Relay Ratings:
  • Rated current: Typically 5A (adjustable) or 1A for different systems.
  • Rated voltage: 110-250V AC or DC.
  • Operating temperature: -20°C to +60°C.
  • Power supply: Typically 24V DC, 48V DC, or 110V DC, depending on configuration.
• Environmental Specifications:
  • Ambient Temperature Range: -20°C to +60°C.
  • Relative Humidity: 5-95% (non-condensing).

Product Use:

The GE Multilin SR469-P5-HI-A20-H relay is used in industrial applications, particularly for protecting:

1. Generators: It can protect both the generator and its associated transformers and circuits.
2. Motors: For protection against conditions like overload, under-voltage, or over-voltage.
3. Transformers: Differential protection for transformers is one of the key features.
4. Industrial Power Systems: Any system requiring comprehensive protection for electrical equipment such as motors, generators, and transformers.

The relay is designed for use in high-reliability environments where it helps to:

• Reduce downtime due to equipment failure.
• Protect expensive equipment from damage due to electrical faults.
• Enable remote monitoring and diagnostics to enhance operational efficiency.

This relay is typically found in power generation, distribution networks, heavy industries, and large commercial installations.
