Products

Implement Ethernet network connections with reliable fiber-optic or shielded-twisted-pair (STP) copper cables.

Distribute IRIG-B time to SEL products and other devices, and connect GPS and radio antennas to SEL devices with an antenna connection.

SEL integrates multiple pieces of equipment and hardware (from SEL and other vendors) into a single assembly or kit, enabling one-stop shopping for parts and labor with a quick turnaround time.

SEL designs, manufactures, tests, and delivers custom protection, control, and metering panels as well as control cabinets and retrofit doors. SEL panels are supported by an unmatched warranty and extraordinary customer service. Panels, cabinets, and doors are built to match customer specifications and needs.

SEL provides reliable finished (terminated) cables, built to IPC workmanship standards in our ISO 9001 certified plants – And, they are covered by our worldwide, ten-year warranty. A variety of standard and customized twisted pair and coaxial cables and connector combinations are available from SEL.

The SEL ICON is a wide-area-networking multiplexer optimized for industrial and utility applications. ICON virtual synchronous networking (VSN) preserves the performance characteristics of time-division multiplexing (TDM) when converting to Ethernet as a transport protocol. By combining TDM and Ethernet transport options with a comprehensive range of data interfaces, the ICON makes it easy to migrate legacy network technologies to a converged IT/OT packet-based solution.

SEL sells wall-mount AC power supplies as accessories for communications and networking equipment. These AC power supplies are commercial temperature rated and appropriate for testing and office environments.

The RadioRANGER solution reduces the need to access vaults or open pad-mounted enclosures to retrieve the FCI status, decreasing fault-locating time and improving utility personnel safety.

SEL Underground AutoRANGER Fault Indicators are reliable, self-adjusting, settings-free faulted circuit indicators suitable for applications with fault current ranging from 50 A to greater than 1,200 A. They are designed for a variety of underground applications and can be paired with a range of display options.

Economical timed-reset fault indicator eliminates false reset concerns.

Select your trip value in the field. Stock one fault indicator for a variety of system conditions.

Line-powered fault indicator provides years of maintenance-free operation.

Load current-powered faulted circuit indicator (FCI) with no minimum voltage requirement provides a solution for low-voltage applications.

Install current monitoring sensors without interrupting service.

Battery-free automatic reset fault indicator provides maintenance-free fault indication.

Troubleshoot problematic sections of overhead systems.

Apply the SEL-FLT and SEL-FLR Fault and Load Transmitter and Receiver System to improve distribution system reliability metrics and customer satisfaction. The SEL-FLT Fault and Load Transmitter operates using 900 MHz wireless sensors that continuously monitor the line for faults while providing load data with 2 percent accuracy to the SEL-FLR Fault and Load Receiver, with a range of up to 10 miles. Speed up system restoration by pinpointing faults and knowing where to send repair crews. Accurate and real-time load monitoring enables improved switching decisions, since operators confidently know which viable alternate feeders are available to pick up the impacted customers.

Reliable ground fault detection for three-conductor cable applications.

Provide auxiliary dc power to your protective relays in the classroom or lab.
