Installation Support
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.
Panels and Enclosures
Pre-engineered or custom panels and enclosures help keep costs low and increase system reliability when used for retrofit upgrades and new equipment installations.
Cables
These cables connect SEL products to other devices, including relays, information processors, computers, I/O modules, clocks, switches, and modems.
Power Supplies
SEL power supplies provide reliable power to devices in the field or in a workbench setting.
Control Devices
SEL control and wiring devices decrease maintenance costs and increase reliability.
Testing
These devices allow you to test SEL protective relay features, including traveling-wave fault locators and Mirrored Bits functions.
