An SEL solution can help you meet the highest standards for reliability and security—while also reducing the lifetime cost of ownership.
Use SEL products to:
A turnkey point of common coupling (PCC) solution. One low-cost device controls your utility interconnection with IEEE 1547-2018 protection and synchronization. SEL’s innovative fast islanding detection ensures safety on both sides of the intertie point.
SEL Grid Connect is an add-on feature available with SEL Real-Time Automation Controllers (RTACs). It is designed to simplify interconnection control and solve common interconnection challenges, such as adapting for varying cloud cover, nonresponsive inverter controls, and unexpected voltage excursions.
Optimize your system by analyzing data, identifying usage trends, and diagnosing system problems.
A hardened computer with error-correcting code (ECC) memory technology and no moving parts, the SEL-3360 is tested to the same standards as our protective relays and has ten times the mean time between failures (MTBF) of typical industrial computers.
Our most powerful automation controller—ideal for automation and integration of generation systems, both large and small.
An easily customizable automation controller with flexible communications and I/O options, the SEL-2411 integrates with SCADA and plant control systems and facilitates sequential events reporting, station integration, remote monitoring, and ac metering.
Accurate, secure time distribution for protection and synchronization. Receive Global Navigation Satellite System (GNSS) time signals, and distribute precise time via multiple output protocols, including IRIG-B and the Network Time Protocol (NTP).
SEL communications solutions help ensure that your communications networks are reliable, cybersecure, and compliant with NERC CIP auditing requirements.
The industry’s first field-hardened software-defined networking (SDN)-enabled switch. Centralized, software-controlled traffic engineering puts you in control of your communications flows and helps secure the cyber and physical interfaces.
A wide-area networking multiplexer optimized for utility and industrial applications. The ICON is configurable for SONET or Ethernet transport. It is also ideal for migrating legacy network technologies to a converged network solution.
Provide Ethernet connectivity and secure network management for SCADA, engineering access, and control.
A router, VPN endpoint, and firewall device, the SEL-3620 provides enhanced security for your control systems and critical cyber assets. It supports NERC CIP compliance efforts without needing Technical Feasibility Exceptions (TFEs).
Let us partner with you to create an SEL solution for your system. From engineering studies and system design through commissioning and training, SEL engineers bring inventiveness and a deep understanding of the fundamental principles of electric power systems to every project. No matter how complex or sophisticated the system, we can help you protect, simplify, and control it.
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.
SEL 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.
Technical support for SEL-manufactured devices is always free. No matter how often you need to call or how long your SEL products have been in service, you’ll reach an SEL expert who can provide the service and support you need.
Our cybersecurity team is always ready with the information and resources needed to keep your OT networks and critical systems secure and working effectively. Cyber services support contracts can include incident response, audits, system hardening, and more, depending on your anticipated needs.
