Multilin L90 GE FANUC Line Current Differential System

Description

The Multilin L90 GE FANUC Line Current Differential System is a specialized line protection device designed for electrical power transmission infrastructure. It delivers high-speed current differential protection suitable for transmission lines and cables across all voltage levels, while also supporting complete distance protection and dual-breaker applications, compatible with both single-pole and three-pole tripping operations. A key feature is its synchronized sampling at each relay, which minimizes the impact of communication channel issues to maintain reliable protection performance. The system’s differential element incorporates adaptive restraint technology, balancing sensitivity for internal fault detection and security against incorrect tripping during external faults. It supports inter-relay protection communications via direct fiber connections and multiple interface options, ensuring flexible integration with existing network setups. This system is engineered to address the core protection needs of overhead transmission lines and underground cables, providing robust, adaptive protection that adapts to varying fault conditions while mitigating risks associated with communication limitations.
