GE Introduces the L90 Series of Advanced Relay Protection Devices to Ensure Safe and Stable Power Grid Operation

Product Overview

The GE L90 series relay protection devices are high-performance current differential protection systems suitable for transmission lines and cables of all voltage levels. The core advantages of this series include:

· High-speed Response: Utilizes advanced digital signal processing technology to detect faults within milliseconds and take immediate action, ensuring rapid grid recovery.

· High Reliability: Features built-in multiple redundancy designs, including power supply, processor, and communication modules, to ensure stable system operation even under extreme conditions.

· Flexible Configuration: Supports multiple communication protocols and interfaces, making it easy to integrate into existing SCADA systems and substation automation systems.

· Intelligent Diagnosis: Equipped with powerful fault diagnosis and recording functions, it can monitor system status in real-time and generate detailed fault reports to assist operation and maintenance personnel in quickly locating and solving problems.

· Strong Scalability: Modular design allows users to add or replace modules as needed, enabling flexible system expansion and upgrades.

Application Scenarios

The L90 series relay protection devices are widely used in various areas of power systems, including but not limited to:

· High-Voltage Transmission Lines: Suitable for high-voltage transmission lines up to 500kV, providing comprehensive protection functions.

· Cable Protection: Ideal for underground and submarine cables to ensure their safe operation.

· Substation Automation: Acts as a core component of substation automation systems, working in tandem with other protection devices and monitoring equipment to achieve comprehensive grid protection.

· Industrial Power Systems: Suitable for the power systems of large industrial enterprises to ensure the normal operation of key equipment.
