GE 369-HI-R-0-0-0-0-E

Description

• Storage Temperature Range: -40°C to +85°C, ensuring stability during transportation and long-term storage
• Communication Interfaces: Equipped with Ethernet (IEEE 802.3) for remote monitoring and control, and RS485 (Modbus RTU) for local device communication
• Protection Level (Enclosure): IP20 for the relay unit (suitable for indoor cabinet mounting); optional IP65 enclosures available for outdoor applications
• Certifications: Complies with IEC 60255 (International Electrotechnical Commission standards for protective relays), UL 508 (safety standard for industrial control equipment), and CSA C22.2 No. 14 (Canadian safety standard for control equipment)

Functional Features

• Comprehensive Protection Functions: Integrates multiple protection elements, including overcurrent protection, overvoltage protection, undervoltage protection, differential protection, and frequency protection, to cover common fault scenarios in power systems.
• High-Speed Fault Detection and Tripping: Utilizes advanced digital signal processing (DSP) technology, achieving fault detection within milliseconds and initiating tripping actions to minimize damage to electrical equipment.
• Real-Time Monitoring and Data Logging: Continuously monitors key electrical parameters (current, voltage, power, frequency, etc.) and logs historical data (fault records, event logs, and operational data) with a storage capacity of up to thousands of events.
• Flexible Configuration and Programming: Offers a user-friendly configuration interface (via GE’s dedicated software, such as UR Setup) to customize protection settings, trip delays, and logic equations based on specific power system requirements.
• Remote Control and Diagnostics: Supports remote access through Ethernet, enabling operators to adjust settings, retrieve data, and perform diagnostic tests without on-site intervention, reducing maintenance costs and downtime.
• Self-Monitoring and Fault Alarm: Features built-in self-check functions for internal circuits and components; triggers audible/visual alarms or sends digital signals to the control system if internal faults (e.g., power supply failure, communication loss) occur.
• Compatibility with Power System Automation: Seamlessly integrates with SCADA (Supervisory Control and Data Acquisition) systems and substation automation platforms, facilitating centralized management of power grids.

Application Scenarios

• Power Substations: Used to protect and monitor transformers, circuit breakers, and busbars in medium-voltage (MV) and high-voltage (HV) substations, ensuring the stable operation of the power transmission and distribution network.
• Industrial Power Systems: Deployed in manufacturing plants (e.g., steel mills, chemical plants), data centers, and industrial parks to protect critical electrical equipment (motors, generators, and power distribution panels) from electrical faults.
• Renewable Energy Installations: Applied in solar power plants and wind farms to protect inverters, transformers, and grid-connection points, ensuring safe integration of renewable energy into the main power grid.
• Commercial and Residential Power Distribution: Used in large commercial buildings (shopping malls, office towers) and residential communities to protect power distribution cabinets and prevent electrical fires caused by overcurrent or short circuits.
• Transportation Power Systems: Integrated into railway power supply systems, port cranes, and airport ground support equipment to protect electrical circuits and ensure reliable power supply for transportation operations.
