About this item
SEL SEL-387L Line Current Differential Relay
USED product out of manufacturer's box
Model: SEL-387L
A line current differential relay is a device used to protect electrical systems against short-circuit faults or differential overloads. It monitors the difference between the input and output currents of an electrical system, such as a transformer, motor, or transmission line, and acts to shut down the system if this difference exceeds a predetermined value.
Use SEL-387L Line Current Differential Relays for economical and easy-to-apply line protection.
Line Current Differential Protection – Protect two-terminal transmission and sub-transmission lines with current transformers (CTs) of the same ratio at each end. Apply a 64 kbps digital communication channel for complete phase and ground fault protection with simple settings.
Differential Communications—Apply the SEL-387L Line Current Differential Relay with a multiplexed communication system using single-mode fiber optics or the integrated IEEE C37.94-compliant connection. Connect to EIA-422 and G.703 multiplexers using the SEL-3094 Interface Converter.
Easy application
Protect two-terminal transmission and sub-transmission lines with CTs of the same ratio at each end. Apply a 64 Kb digital communication channel for complete phase and ground fault protection with no settings.
Simple installation
Connect single-mode, 1300 and 1550 nm fiber optics for distances up to 120 km without a repeater. No additional transceivers are required.
Flexible Communications
Apply the SEL-387L with a multiplexed communication system using the integrated IEEE C37.94-compliant connection. Connect to EIA-422 and G.703 multiplexers using the SEL-3094 Interface Converter.
Low-cost replacement for obsolete systems
Use the SEL-387L for complete two-terminal line protection. Save money with low equipment costs and no configuration costs. Replace error-prone pilot-wire relays with a sensitive and secure fiber-optic line current differential relay. Use the integrated communications monitoring and alarm system to improve protection quality.
acSELerator Software
Develop offline relay settings, program SELogic control equations, and analyze post-fault event reports.
