english introduction:

MULTILIN L9OTB5HLHF8LH6 is a differential relay system in the MULTILIN series of GE (now GE Smart Grid). This system is dedicated to differential protection in power systems, mainly used to detect and protect differential current anomalies in transformers, generators, and other critical equipment.

Main features and functions

Differential protection function

Differential current detection: Monitor and compare the current difference between the input and output terminals to detect possible differential faults, such as winding short circuits or ground faults.

Quick fault response: When the differential current exceeds the set range, an alarm or protective action is quickly issued to prevent equipment damage.

Protection settings

Flexible configuration: allows users to configure protection parameters based on specific device and application requirements, such as differential current settings, time delays, etc.

Multi level protection: Supports multi-level protection settings to provide more refined protection strategies and higher system reliability.

Communication and Integration

Supports multiple protocols: compatible with common communication protocols such as Modbus, DNP3, IEC 61850, etc., facilitating integration with other systems.

Network interface: Provides network interfaces to achieve remote monitoring and data exchange, improving the flexibility of system management.

user interface

Graphic display: equipped with an intuitive graphical user interface for easy configuration, monitoring, and viewing of the status of the protection system.

Alarm and indicator lights: Provide clear alarm signals and indicator lights, and provide real-time feedback on the system's operating status and fault information.

Reliability and Durability

Industrial grade design: designed to adapt to various industrial environments, with high durability and stability.

Self diagnostic function: With self diagnostic capability, it can quickly detect and report problems in the system, ensuring reliable operation.

application area 

Substation: Used for differential protection of transformers and other critical equipment in substations to ensure the safe operation of the equipment.
