The scalable, modular nature of SEL automation solutions allows you to implement a broad set of functionalities or choose a subset and add more capabilities over time.
Plus, when you choose SEL, you get more than just a product—you get the industry’s best customer service and technical support.
SEL automation solutions are ideal for:
SEL Engineering Services provides automation solutions that improve reliability, increase operational efficiency, and reduce operation costs.
We can design and implement a broad set of functionalities or a subset that addresses your specific needs. Our scalable, modular distribution automation controller (DAC) integrates with the IEDs already in your system—and we can also provide protective relays, recloser controls, secure communications, and other equipment as part of the solution, depending on your needs.
Increase system reliability and operation efficiency using SEL automation controllers, which offer scalable and modular solutions for data concentration, protocol conversion, and more.
Our automation controllers and communications equipment are tested to the same durability standards as our relays and carry the same ten-year warranty.
The SEL-3530 RTAC provides complete and flexible system control with integrated security, seamless configuration, and unified logic. The SEL-3530-4 is a compact version of the SEL-3530 that is small enough to be installed in recloser cabinets.
Improve fault location throughout your distribution system. This line-powered wireless transmitter and receiver system is flexible and easy to deploy.
The SEL-3505 controller is a lower-voltage version of the SEL-3530 RTAC. The SEL-3505 RTAC is compact and delivers all the standard features of an RTAC.
The SEL-3555 is the fastest and most powerful RTAC for advanced data concentration and control.
Remote data acquisition in a rugged, modular platform. Choose versions with 4 or 10 slots, and mix and match the I/O modules to fit your application. Each Axion becomes a node in your control network, sending deterministic fiber-optic communications to remote terminal units (RTUs) and relays.
Apply this system with your existing protection schemes to help relays make better tripping and reclosing decisions based on the location of the fault. The wireless fault transmitter and receiver provide a flexible, economical way to enhance distribution protection and improve the reliability and safety of your feeder lines.
Modernize your substation with an SEL digital secondary system solution (commonly called a digital substation solution). Our digital secondary systems improve safety and reduce costs by moving high-energy signals out of the control house and reducing copper wiring.
SEL products are designed and manufactured for the world’s most challenging environments, exceeding all industry standards for temperature, shock, and electric stress. An optional conformal coating for circuit boards adds an extra level of protection against contaminants in extreme environments.
Every SEL product comes with a ten-year warranty—the best in the industry. If any product fails under warranty, we’ll repair or replace it for free.
We’re happy to answer all your questions and help develop the best solution for your needs.
Every SEL solution comes with lifetime technical support, free of charge.
There are no service contracts, time limits, or expiration dates. No matter how often you call or how long your SEL products have been in service, you’ll reach a friendly human who can provide the service and support you need.
Our support teams are stationed in regional offices around the world and staffed with application engineers who are experts in our products and in power system applications. We’re always ready with the information and resources needed to keep your SEL solution working effectively.
