Description
Overview
The L30 is a cost-effective line current differential protection relay. It is designed for sub-transmission and medium-voltage lines and cables. The relay ensures reliable and secure operation even in the harshest power system conditions.
Key Benefits
- Proven current differential protection offers secure, high-speed tripping for reliable fault detection and clearance.
- It features advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation. This includes complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 Hardfiber). These features ensure interoperability, optimize device management, and reduce ownership costs.
- Routable GOOSE (R-GOOSE) enables GOOSE messages to travel beyond the substation. This enhances wide-area protection and control applications.
- The dynamic charging current compensation and communication channel asymmetry compensation increase sensitivity.
- The adaptive restraint characteristic protects against errors, including CT saturation.
- The Phasor Measurement Unit (synchrophasor) supports IEEE C37.118 (2011) and IEC 61850-90-5 standards.
- CyberSentry™ security features meet modern industry cybersecurity requirements.
- The relay offers application flexibility with multiple I/O options. These include high-density I/O, programmable logic, modularity, and customization.
- A large, full-color display provides real-time visualization and control of the protected bay. It includes a bay mimic, annunciator functionality, and graphical phasor visualization.
Applications
- Overhead lines and underground cables of various voltage levels.
- Circuits with tapped transformer feeders.
- Three-terminal line configurations with channel redundancy and direct transfer tripping (DTT).
- Wide-area system monitoring and control using integrated protection and synchrophasor measurement.
- Three-pole autoreclosing and independent synchrocheck supervision.
