An SEL solution can help you meet the highest standards for reliability and security—while also reducing the lifetime cost of ownership.
SEL solutions are ideal for:
An SEL-700G series relay configured especially for wind generation applications with two sets of overcurrent elements for dual-feeder protection. The SEL-700GW offers complete generator protection with flexible I/O, advanced communications capabilities, and an optional autosynchronizer function.
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.
The versatile SEL-487V, with application-specific settings, is ready for your capacitor bank applications. Its real-time control system uses synchrophasor data, an IEC 60255-149-compliant thermal model, and advanced logic to eliminate the need for additional devices.
Optimize your system by analyzing data, identifying usage trends, and diagnosing system problems.
Remote data acquisition in a rugged, modular platform. Choose versions with 4 or 10 slots, and mix and match the modules to fit your application. Each Axion becomes a node in your distributed generation network, sending deterministic fiber-optic communications to a relay or automation controller.
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).
Annunciation of alarms and system events—plus programmable logic, communications support, a Sequence of Events recorder, and a software HMI.
Our most powerful automation controller—ideal for automation and integration of generation systems, both large and small.
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.
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.
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.
