Digital Secondary Systems
-
Schweitzer Engineering Laboratories, Inc.
SEL digital secondary system solutions (sometimes called digital substation solutions) help protect and control substation primary equipment using digital devices in the secondary system that transmit data via fiber-optic cables. Our flexible, scalable, and economical solutions are built with rugged, field-tested hardware that can withstand harsh environments. Select from two solutions:
-
Product
Installation Support
-
Schweitzer Engineering Laboratories, Inc.
Completing a substation, panel, or a control house requires more than relays. SEL provides contact arc suppressors, linear power supplies, displays, selector switches, panel-mount hardware, bezels, dust covers, cables, and other accessories essential for a successful power system project.

Product
Electrical Balance Of Plant
-
Schweitzer Engineering Laboratories, Inc.
Protecting a generation facility encompasses more than just protecting a generator. Protecting motors, feeders, and station-service equipment is also critical to maintaining plant uptime. By combining SEL solutions, you can do all of that using reliable, field-proven hardware that is suited for use in utility-, industrial-, and commercial-scale power systems.

Product
Operational Technology (OT) Networking
-
Schweitzer Engineering Laboratories, Inc.
OT networking solutions provide communications with the performance, cybersecurity, and ruggedness required for demanding operational applications.
-
Product
Encryption
-
Schweitzer Engineering Laboratories, Inc.
SEL communications devices encrypt data streams for security.
-
Product
Routers
-
Schweitzer Engineering Laboratories, Inc.
Routers forward data packets to and from different networks. In utility networks, routers are often used to create security perimeters around substation LANs.
-
Product
Arc-Flash Protection
-
Schweitzer Engineering Laboratories, Inc.
Arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, thereby reducing hazardous incident energy. Combining light-sensing technology with fast overcurrent protection provides high-speed arc-flash detection and prevents overtripping for external faults. Arc-flash protection relays work with low- and medium-voltage apparatus and easily coordinate with other devices in utility-, industrial-, and commercial-scale power systems.
-
Product
SCADA
-
Schweitzer Engineering Laboratories, Inc.
SEL SCADA systems offer improved reliability and performance, streamlined access to valuable information, and expanded power system management capabilities.
-
Product
Transceivers
-
Schweitzer Engineering Laboratories, Inc.
Transceivers convert between copper and fiber optics or between other communications interface standards.
-
Product
Generator Relay
SEL-300G
-
Schweitzer Engineering Laboratories, Inc.
Apply the SEL-300G Relay for comprehensive primary and backup generator protection.
-
Product
Security Gateways
-
Schweitzer Engineering Laboratories, Inc.
Security gateways combine cybersecurity capabilities to create secure access paths through security perimeters.
-
Product
Current Differential Relay
SEL-587
-
Schweitzer Engineering Laboratories, Inc.
The SEL-587 Current Differential/Overcurrent Relay provides protection for any two-input apparatus, such as transformers, motors, generators, and reactors. Apply it for differential and overcurrent protection and use event reports for quick post-event analysis.
