As part of its normal functionality, the SEL-411L provides line current differential and distance protection for transmission lines View and Download Sel 411L instruction manual online Disconnect status inputs and voltage elements can enable high-speed stub bus protection and proper response toward remote SEL-411L relays.
SEL adds TiDL and Sampled Values technologies to SEL411L line. Schweitzer Engineering Laboratories has added both Time-Domain Link (TiDL) technology and Sampled Values (SV) technology to the SEL-411L Advanced Line Differential Protection, Automation and Control System For breaker-and-a-half, ring-bus, or double-bus double-breaker bus applications, the SEL-411L-2 provides proper security for the 87L function by supporting two current inputs for individual measurements of each breaker.
