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).
