Cable Fault Locator

alternative

Overview

Cable fault location is the process of locating periodic faults, such as insulation faults in cables. In this process, mobile shock discharge generators are among the devices used.

Cable faults are damage to cables which effect a resistance in the cable. If allowed to persist, this can lead to a voltage breakdown. There are different types of cable faults, which must first be classified before they can be located.
