GE \/ Alstom Multilin L30 Relay Line Current Differential System<\/h1>\n

GE Multilin L30 Relay is a cost-effective line current differential protection relay intended for sub-transmission and medium voltage lines and cables providing reliable and secure operation even under the worst case power system conditions. The L30 provides secure high-speed fault detection and clearance suitable for three-pole tripping applications. The L30 supports inter-relay communications via direct fiber as well as standard RS422, G.703 and C37.94 telecommunication interfaces. The L30 also provides synchrophasor measurements over Ethernet per IEEE C37.118.<\/p>\n

GE Multilin L30 Relay Key Benefits<\/h2>\n

\u2022 Proven current differential protection ensures secure high-speed tripping
\n\u2022 Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
\n\u2022 Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
\n\u2022 Increased sensitivity through dynamic charging current compensation and communication channel asymmetry compensation
\n\u2022 Adaptive restraint characteristic provides excellent security against measurement errors including CT saturation
\n\u2022 Phasor Measurement Unit (synchrophasor) according to IEEE\u00ae C37.118 (2011) and IEC\u00ae 61850-90-5 support
\n\u2022 Application flexibility with multiple I\/O options including high density I\/O, programmable logic, modularity, and specific customization
\n\u2022 An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors<\/p>\n

Applications<\/strong>
\n\u2022 Overhead lines and underground cables of different voltage levels
\n\u2022 Circuits with tapped transformer feeders
\n\u2022 Suitable for three-terminal line configurations, with channel redundancy and direct transfer tripping (DTT)
\n\u2022 Wide area system monitoring and control and using integrated protection and synchrophasor measurement
\n\u2022 Applications requiring three-pole autoreclosing and independent synchrocheck supervision<\/p>\n
