During excavation projects, it is extremely important to make sure to not cause any damage to the wires and other services that are buried in the Earth due to previous works. It is an important precaution to take and the most basic matter to deal with.
Although, the question remains, how do you identify the location of such cables and underground services? The answer is simple, by using a cable locator.
If your hidden or buried wire is not working, it’s time for you to track down the error with the cable locator of your choice and convenience. The error is most probably due to a break in your wire – and a cable locator will help you locate it. The most strenuous part is finding the damaged part of the wire and these wire locators will make it a piece of cake for you! On the other hand, fixing the break is rather simple and less of a problem. Once that is done, your wire is ready to do its work again!

What is a cable locator?
A cable locator is an instrument that has been used by the people in order to detect the presence and give an estimated location of the wires and other underground services without actually having to dig it up. This process helps in avoiding any unnecessary damage and causes less inconvenience to others.
These instruments are widely used in various aspects of electrical work such as communication cable construction, electrical cable construction, building pipeline construction, telecommunications cables, power supply circuits and electric line maintenance.
How does it work?
The cable locators detect the electromagnetic signals that are emitted by the utilities present underground. They then amplify these signals and then give us the desired information about the location of these services.
Radio frequencies, metal detectors and underground radars are also used in order to measure the location of the same.
The system of cable locator has a transmitter that is used to send a signal down the cable being traced or to a solenoid valve that is being located. A receiver is later on used to pick up the signal and follow the cable or locate the coil.
Certain specifications to be careful about:
You will need a lot of variations in the range of the frequency inorder to get as close to the accurate location as possible. Start from the lowest and keep increasing to get the best results.
- Detection Range
Make sure to check the depth that the cable locator can reach. Choose a cable locator that can give you an accurate measurement of the depth that the underground service is located at.
- Mode of detection
There are two different modes for locating a cable — active and passive. In the active mode, a particular line can be easily found by injecting a specific frequency signal. On the other hand, in the passive mode, unknown lines can be found using the electromagnetic signals emitted without injecting a frequency signal. Energized cables can be easily found with this method.
- Null or Peak or differential mode
Most devices use sound in order to give information about the completion of a task. This device too, does the same. In the null mode, the devices make a sound the entire time and only stops when the location has been determined. For the peak mode, the device makes a sound only when the location of the cable has been found. The differential mode, however, makes a sound depending on the proximity of the wire or cable.
One has to be careful about these specifications in order to make the right choice. Some other things that need to be kept in mind are the display, current measurements and the stick. Display is important to make sure you can perceive the information clearly and accurately.
That completes the list of all the cable locators we recommend! It is now up to you to choose the right device for this meticulous task! If you are not sure on the instructions to the device, it is highly recommended to take the help of an expert. Better be safe than sorry!
