Product Name:
GE Multilin SR469-P5-HI-A20-H Protection and Control Relay
Product Description:
The GE Multilin SR469 is a digital protection and control relay designed for use in the protection of generators, transformers, motors, and other industrial equipment. The relay provides a comprehensive suite of protection and monitoring functions including overcurrent, differential protection, voltage, frequency, and other customizable protection settings.
Product Parameters / Specifications:
- General Protection:
- 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:
- Generators: It can protect both the generator and its associated transformers and circuits.
- Motors: For protection against conditions like overload, under-voltage, or over-voltage.
- Transformers: Differential protection for transformers is one of the key features.
- 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.
