EasiLinc ELTLL Transmission Line Current Differential Protection Module

The ELTLL module offers transmission line current differential protection, zone distance protection, directional overcurrent protection, communication-aided tripping schemes, reclosing and sync check functions. This module is based on the popular SEL-311L Relay, but is much simpler to implement and use. No logic settings are needed to place the ELTLL package in service.

Every ELTLL protection module includes:

• Protective relay and test switches, mounted and pre-wired in a 19 inch panel

• Supporting schematics, provided in several electronic formats to document the relay connections to the system

• Application setting files to define the logic, event reporting, load profiling, integration, etc. needed to provide full relay functionality.
