Power Quality Measurement & Digital Fault Recording
In view of the growing number of factors with a disturbing influence on power systems and the ever increasing sensitivity of devices and installations on the consumer side, simple monitoring criteria such as undervoltage or overcurrent are no longer adequate. Reliable registration of all the relevant processes within the electrical power system calls for constant observation of a wide variety of derived parameters, such as individual harmonic content, system unbalance and interharmonics, and the swift identification of even slight deviations from the norm.

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.

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.
