Distribution Protection

Feeder protection solutions offer comprehensive overcurrent and arc-flash protection capabilities suitable for all types of utility-, industrial-, and commercial-scale power systems. 

SEL devices protect valuable transformers in power generation systems, including generator step-up transformers.

Protect busbars and switchgear with high-speed differential fault detection, or expand your protection with features such as restricted earth fault, arc-flash, and overcurrent elements.

Recloser controls provide fault location, isolation, and system restoration using protection and communications capabilities.

Time-Domain Link (TiDL) technology and SEL Sampled Values (SV) technology help protect and control substation primary equipment using digital devices in the secondary system that transmit data via fiber-optic cables.

Arc-flash protection relays work with low- and medium-voltage apparatus and easily coordinate with other devices in utility-, industrial-, and commercial-scale facilities.

Downed-conductor detection technologies can detect many high-impedance faults on a distribution system, improving safety as well as mitigating wildfire risk.

Remote I/O modules transfer data from remote locations over fiber and expand the I/O of SEL relays, automation controllers, and other devices without modification to the control panel face.

SEL software helps you optimize the configuration of your device and visualize power system events.

Pre-engineered or custom panels and enclosures help keep costs low and increase system reliability when used for retrofit upgrades and new equipment installations.

Complete your project with power supplies, switches, panel-mount hardware, cables, and other accessories.
