Reduce Fault-finding Time by 50% or More

Systematically-applied fault indicators reduce fault-finding time by 50% or more, making them a powerful tool for improving reliability indices such as CAIDI (Customer Average Interruption Duration Index). Shorter outages mean reduced costs to utilities and their customers.

Reclosing and sectionalizing to find the location of a fault puts line crew safety at risk. Use fault indicators for faster, safer fault finding.

SEL has a solution for your application. Choose from overhead or underground models; LED, target, or radio frequency indication; and a variety of clamp and reset options. Remote displays on underground fault indicators eliminate the need to open an enclosure to determine the fault indicators’ status, saving time and making life easier for troubleshooters.

Choose a battery-free or non-replaceable battery fault indicator for zero maintenance over the product’s 15+ year lifetime. Durable construction and automatic reset mean that SEL fault indicators do not require Operations attention–unless they’re doing their job of leading a line crew to the location of a fault.

Apply timed reset fault indicators and fault counters in areas affected by momentary outages, and flickering lights as an efficient means of locating temporary faults. Using fault indicators reduces costs and improves distribution reliability. The Overhead AutoRANGER differentiates between temporary and permanent faults with distinct displays.

Applying fault indicators at the midpoint of a feeder allows troubleshooters to restore power to the unaffected portion of the system…even before identifying the exact location of the fault. SEL fault indicator customers applying a midpoint sectionalizing method experience improved reliability and reduced customer outage time.

SEL relays calculate the distance from the station to a fault…but not which tap or branch the fault is on. Fault indicators complete the job by leading the line crew down the correct tap so that they can restore power faster and spend less time in the field looking for the specific location of the fault.

All fault indicators manufactured by the E. O. Schweitzer Manufacturing Division of SEL come with a 5-year “no questions asked” warranty, the best in the world for fault indicators.

SEL fault indicators install without the use of special tools, straps, screws, or complicated clamping mechanisms.
