Power Company Implements Digital Secondary System That Uses SEL TiDL Technology
Learn how a power company worked with SEL to design a digital secondary system (DSS) that uses a reliable, secure Time-Domain Link (TiDL) process bus solution.
Utility and industrial companies require operational efficiency and reliability to meet modern energy requirements. As part of a substation modernization initiative, a power company needed a DSS that could scale as the substation expanded over time—without increasing configuration complexity or requiring extensive networking infrastructure. Learn how the company worked with SEL to implement a solution that enables time-deterministic data exchange, simplifies configuration, and supports a fast, safe, and secure deployment.
Bring Speed and Simplicity to Your Process Bus

A TiDL technology solution is simple, requiring no network engineering or high-accuracy clocks for critical protection functions. It uses a point-to-point fiber architecture to transmit data from SEL-TMU TiDL Merging Units in the yard to SEL TiDL relays in the control house. Learn how TiDL technology brings speed and simplicity to next-generation substations.
