Fault Indicators, Sensors and Current Transformers

Overhead faulted circuit indicators include easy-to-spot displays to help direct line crews to the faulted line sections—enabling faster restoration of power and improved customer uptime.

These products enhance distribution protection by helping relays make better tripping and reclosing decisions based on the location of a fault.

Underground faulted circuit indicators identify the faulted cable section—without a time-consuming re-fuse and sectionalize process. Applications include subsurface or pad-mounted transformers, switchgear, sectionalizing cabinets, junction boxes, and splices.

SEL-CTs are designed for applications where it is difficult or uneconomical to open the primary conductor to install a solid-core-type current transformer. 

SEL offers a variety of sensors that can improve distribution system understanding and troubleshooting. We also offer tools for testing and resetting faulted circuit indicators.
