It should be noted that the majority of modern communities presently utilize underground electrical cables to distribute electricity to homes. Nonetheless, in past years we used to use overhead cable and utility poles. These days to light parking areas it is preferred to use underground electrical cable. Additionally many house owners use this types of wires to power outbuildings. Though underground installations also have their issues, but they are less frequent than overhead installations. In fact there major disadvantage is that underground cable does degrade over time and break.
Another important detail is that underground cable is subject to breaks, called faults. As a rule such brakes are caused by any number of things. For instance if you install a cable in rocky terrain it is especially susceptible to breakage. Besides, there are some more subjects that may cause damage to cables. Primarily, these are people digging into the cable while installing something else. One more thing that may cause the problems of this type are ground shifts during freeze/thaw periods. Furthermore the cable can be damaged during the installation. Like I said all electric cable degrades over time and will eventually develop problems.
Let’s try to see what can be done in the case of cable being damaged? Indeed, I would recommend you nothing else than calling a professional. I want to admit that only a professional can locate the underground cable and the break for you. The reason is that for this kind of job the expensive equipment is needed, so it’s recommended leave the work to a professional. Once the professionals arrive they will a cable tester to determine that a break exists.
Then the y will use an underground cable locator to trace the path of the underground electrical cable, and use paint to mark where the cable runs underground. In order to locate the place where the electrical cable is broken, the professionals may use various methods. All, they may use a hill of potential method, to test the area for voltage changes in the ground. Besides an earth gradient method may be used. According to this method the professionals sent a high voltage surge through the electrical cable. By doing so they can detect the place of an electricity leak with a special meter. Remember, you should never use this methods unless you are a professional, because when used by an experienced underground cable specialist, this methods can cause damage.
And finally, it should be noted that although an underground electrical cable is convenient and aesthetically pleasing, in some places you’d better install overhead cable to avoid damage. It’s recommended to use overhead cable in the areas where there is a risk of cable damage.
