Case Study: Power Company achieves faster, safer substation modernization with SEL TiDL
A Schweitzer Engineering Laboratories (SEL) Case Study
a power company installs SEL digital secondary system in 1 day
A power company in North America sought to modernize a substation with a scalable protection and control solution that would reduce configuration complexity and networking infrastructure. To meet this challenge, they partnered with Schweitzer Engineering Laboratories (SEL) to implement a digital secondary system.
Schweitzer Engineering Laboratories provided a solution using its SEL TiDL technology. This point-to-point process bus used TiDL Merging Units to digitize signals and transmit them via fiber-optic cable to relays, simplifying configuration and enhancing cybersecurity. The result was a dramatically faster installation, with the pre-wired breaker cabinet installed in a single day. The solution also improved personnel safety and provided such significant value that the power company has standardized on TiDL and SEL relays for its digital secondary systems.
