Product description
Manufacturer: Multilin
Product No.: L30
The L30 is a cost-effective relay designed for line current differential protection, specifically tailored for sub-transmission and medium voltage lines and cables. It ensures reliable and secure operation even under the most challenging power system conditions. The L30 offers rapid fault detection and clearance suitable for three-pole tripping applications.
Benefits:
Proven Differential Protection: The L30 utilizes proven current differential protection technology, ensuring secure high-speed tripping when needed.
Advanced IEC 61850 Compliance: Certified implementation of IEC 61850 Ed. 1 and Ed. 2, complete settings via SCL files, and flexible process bus support (IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 Hardfiber) ensure interoperability, optimize device management, and reduce the cost of ownership.
Routable GOOSE (R-GOOSE): Enables GOOSE messages beyond the substation, facilitating wide area protection and control applications.
Increased Sensitivity: Dynamic charging current compensation and communication channel asymmetry compensation enhance sensitivity, while adaptive restraint characteristic provides excellent security against measurement errors, including CT saturation.
Phasor Measurement Unit (PMU): Supports synchrophasor measurements according to IEEE® C37.118 (2011) and IEC® 61850-90-5.
Advanced Cybersecurity Features: Incorporates "CyberSentryTM" for enhanced cybersecurity, meeting modern industry requirements.
Application Flexibility: Offers multiple I/O options, including high-density I/O, programmable logic, modularity, and specific customization, ensuring adaptability to various applications.
Applications:
Overhead lines and underground cables of different voltage levels.
Circuits with tapped transformer feeders.
Suitable for three-terminal line configurations, with channel redundancy and direct transfer tripping (DTT).
Wide area system monitoring and control utilizing integrated protection and synchrophasor measurement.
Applications requiring three-pole autoreclosing and independent synchrocheck supervision.
