Spread Spectrum Time Domain Reflectometry, for instance, involves sending down a spread spectrum signal down a wire line to detect wire faults. [10] Several clustering methods have also been proposed to identify the novel fault and segment a given signal into normal and faulty segments.
The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.
A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...

The terminator is usually placed at the end of a transmission line or daisy chain bus (such as in SCSI), and is designed to match the AC impedance of the cable and hence minimize signal reflections, and power losses. Less commonly, a terminator is also placed at the driving end of the wire or cable, if not already part of the signal-generating ...
The Maui wildfire that killed more than 100 people last year and destroyed Lahaina, Hawaii, was caused by downed power lines, investigators found.
Police say the man was traveling north in the 200 block of York Road when his snowmobile collided with a downed utility line. It happened around 8 a.m. Downed power lines, fallen trees and ...
Colored lines, flags, or both are used to mark the location and denote the type of underground utility. A special type of spray paint dispenser, which works when the can is upside-down, is used to mark lines, often in a fluorescent color. On flags, a logo often identifies the company or municipal utility which the lines belong to.
