GE Fanuc L90 Line Current Differential System 100% New and Original

General Electric Multilin L90 Line Current Differential Protection Relay

The General Electric Multilin L90 is a high-end, cost-effective line current differential protection relay designed for transmission lines and cables at various voltage levels. Below are the key specifications:

Functionality

• High-Speed Protection: Provides high-speed current differential protection suitable for transmission lines and feeders.

• Distance Protection: Supports complete distance protection and dual-breaker applications for single and three-pole tripping scenarios.

• Synchronized Sampling: Uses synchronized sampling at each relay to mitigate communication channel issues.

• Adaptive Restraint: Balances sensitivity for internal faults and security during external faults.

• Inter-Relay Communication: Supports inter-relay protection communications via direct fiber and different interfaces.

Protection Features

• Phase-Segregated Differential Protection: Ensures secure high-speed single-pole tripping.

• Phase and Ground Distance Protection: High-speed phase and ground distance (5 zones) with independent compensation settings.

• Sensitivity Enhancements: Increased sensitivity through dynamic charging current compensation and communication channel asymmetry compensation.

• Synchrophasor Support: Phasor Measurement Unit (synchrophasor) support according to IEEE C37.118 (2011) and IEC 61850-90-5.

Communication and Connectivity

• Ethernet Ports: Three independent fiber or copper Ethernet ports for simultaneous/dedicated network connections.

• Time Synchronization: 1 microsecond time synchronization via LAN with IEEE 1588 support.

• Cybersecurity: Advanced cybersecurity features (“CyberSentryTM”) for modern industry requirements.

• IEC 61850 Compliance: IEC 61850 Ed. 1 and Ed. 2 certified implementation with flexible process bus support.

Applications

• Versatile Use: Suitable for overhead lines (including series-compensated lines) and underground cables.

• Three-Terminal Configurations: Suitable for three-terminal line configurations, wide area system monitoring, and control.

• Secure Application: Secure application with Capacitively-Coupled Voltage Transformers (CCVTs).
