Fault Locating
-
Schweitzer Engineering Laboratories, Inc.
The built-in fault-locating methods in SEL devices allow you to quickly identify faults, dispatch crews for repairs, and restore service faster. Traveling-wave fault-locating technology calculates the locations of temporary and permanent faults by measuring the arrival times of the naturally occurring traveling waves caused by a transmission line fault. Accurately detecting these waves requires ultra-high-resolution monitoring, and locating is accurate to within one tower span (±300 m). Impedance-based fault-locating technology calculates fault locations by detecting changes in line impedance as a result of a fault. Impedance-based locating is reliable and accurate to about 2 percent of a line’s total length.

Fault Locator
BIDOYNG
-
BIDOYNG fits into existing LV fuse positions using two LV fuses in parallel, creating a robust single-shot auto-recloser. The primary fuse carries the load current until a fault causes it to operate. Then, after a user programmed delay, the secondary fuse is switched in and the network re-energised without customer interruption.

Visual Fault Locators
-
Optical Wavelength Laboratories
OWL fiber optic visual fault locators (VFL) are specially designed to couple a maximum of optical energy into multimode and singlemode optical fibers by using a bright red fiber optic laser. Breaks, microbends, and other anomalies in optical fibers and connectors cause the intense bright red laser light to escape, thus revealing the presence of a fault. In addition to visual fault location, OWL VFLs can be used as a visual optical fiber identifier. A visual fiber optic identifier eliminates much of the guesswork during testing by identifying the fiber under test.
