Fault Indicators and Sensors Making Electric Pomi Safer, More Reliable, ami Moie Economical

SEL FauLt IndIcator and SEnSor dIvISIon overview In 1950, after presenting ideas and prototypes to Commonwealth Edison in Chicago, Edmund O. Schweitzer, Jr. founded E. O. Schweitzer Manufacturing to design and manufacture line-powered fault indicators. The company, started by SEL founder Edmund O. Schweitzer, III’s father, has been a division of SEL since 2005. In 2011, it became the SEL Fault Indicator and Sensor Division (FISD). SEL will continue to supply utilities around the world with fault indicators and sensors that help reduce fault-finding time, so power can be restored quickly...

Fault Indicators and Sensors Applying SEL Fault Indicators SEL fault indicators sense the magnetic field produced by current flowing through a conductor. When fault current passes through the fault indicator, the fault indicator “trips,” indicating a fault. Because SEL offers a variety of fault indicator displays, the trip might be indicated by a reflective target, flashing light, or combination of the two display types. The Tamperproof Bolt Display, read by a compass-like tool, and RadioRANGER® Remote Fault Reader provide other display options. Normally open point Fault Location Tripped...

FauLt IndIcatorS and SEnSorS Applying Fault Indicators With Other SEL Products Use SEL fault indicators and distribution protection equipment together to identify the location of a fault. When a fault occurs, the SEL feeder relay calculates the fault location as a distance from the substation to the fault, information that could be communicated to a lineman’s cell phone via the SEL-3010 Event Messenger. When a feeder has multiple taps, as shown in the diagram below, the line crew is unable to determine which tap to follow to find the location of the fault. SEL fault indicators provide a...

Overhead Fault Indicators WSO—Wireless Sensor for Overhead Lines This distribution automation sensor stores load and temperature data, and monitors the distribution line for loss of current and fault events. Reports are transmitted to an access point on a communications network using an integrated radio. Key Features Applications • Monitors average load current, ambient temperature, fault threshold, battery status, and history of outages and surge events. • Allows more efficient maintenance scheduling using stored data profiles. • Prevents false tripping with the inrush restraint feature,...

ovErhEad FauLt IndIcatorS AR360—Overhead AutoRANGER® 360° visibility with intelligent display. Key Features applications • Intelligent display allows 360-degree visibility with six ultrabright, wide-angle LEDs that provide overlapping fields of light. • Distinct temporary (amber) and permanent (red and amber) flashing patterns provide flexibility in locating the cause of permanent and self-clearing faults. • Auto-adjusting trip-level selection can detect faults with as little as 50 A of current when loads are light. Automatically steps up its trip threshold up to 1200 A for heavily loaded...

Overhead Fault Indicators AR-OH—Overhead AutoRANGER® Self-adjusting fault indicator for system-wide application—one long-life product for all system loads. This SEL product is GSA approved. Contact your sales representative for pricing and delivery options. Key Features Applications • Reduce engineering time, inventory, and misapplication with self- adjusting trip levels. • Automatically adjusts its trip value based on the load current, eliminating the need to specify a trip value. • Distinct temporary (amber) and permanent (red) fault indications provide the flexibility of tracking down...
