L90A00HCHF8AH6UL6UN6CS6UU6CW2A GE Differential Relay Module

Description

TheL90A00HCHF8AH6UL6UN6CS6UU6CW2Ais a high-performanceline differential protection relayfrom GE’sMultilin L90 series, designed to protecttransmission linesandcablesacross various voltage levels. Built on GE’sUniversal Relay (UR) platform, this model provides secure, high-speed protection with advancedfault detectionanddistance protectioncapabilities. It supportsdual-breaker applications,single-andthree-pole tripping, andIEC 61850 Ed.1/Ed.2for seamless integration into modernsubstation automation systems. The relay usessynchronized samplingandadaptive restraint algorithmsto ensure sensitivity to internal faults while maintaining security during external disturbances.
