An underground cable locator will accurately locate electrical cabling, allowing engineers to conduct cable fault testing or maintenance on cable systems. Underground cable locators use two methods. The first is active location, locating a specific line of cable by injecting a frequency signal via a transmitter and tracing the signal with a receiver as it travels the length of the cable. Passive location is used for non-specific lines, and involves scanning for the electromagnetic field surrounding a cable. Cable locators consist of transmitters and receivers, which receives the electromagnetic fields a transmitter sends through a line. A cable locator will either be able to find a single frequency or locate multiple frequencies. Explore our inventory of underground cable locators below.
