Sometimes the desire to relax in nature outside the city is so great that people just buy their own country house. After the purchase, as a rule, repairs are made, and non-cosmetic, and the cardinal work that affects even the electrical wiring, but this is where difficulties often arise.
In private houses, especially when it comes to old buildings, there are no plans for wiring. As a rule, the entire system is installed in the walls, and it is rather difficult to find it, but you can detect hidden wiring with the help of a detector. This device is divided into many types. It can be purchased both in the construction market and done by hand, even if a person does not have certain skills in electrical engineering.

Basic wiring detector functions
During the repair in a private house may require not only the redevelopment of the electrical system, but there may be problems if you want, for example, to drive a nail, and there passes wiring. In the end, at best will have to open the wall and restore the wiringor it may be that a person will receive a serious injury from the discharge of electricity. Therefore, when working with electrical wiring, you need to use a special device for detecting the electrical system in the wall.
In addition, such a device can be used not only during the repair, but also simply if you wanted to install the decor, or rather, nail the picture or install an additional outlet. The reasons for using the detector, as you can see, can be many. Of course, you can do without a detector, but simply logically guess the location of the wiring, which can go either horizontally or vertically, but this method is sufficient risky. Detector search for hidden wiring allows you to accurately determine the location of all cables.
Types of devices to search for hidden wiring
Nowadays There are a large number of detector modelsdesigned to search for hidden posting. If earlier it was possible to determine only their position, estimate the electrical system plan or simply If you find metal objects in the wall, then modern models can even detect breaks in the wiring. Sometimes it helps a lot, since if the wiring is broken, you don’t have to open the entire wall in search of a defect, but rather just punch a hole in the place of the breakdown. Detectors can also be divided by type:
- search by depth of cables;
- cable material;
- by work time;
- the number of additional functions.
The simplest model is called an electrostatic device. It is cheaper relative to other models and, moreover, is easy to use. Another advantage of this model is that device can detect wiring, grabbing a large radius of the wall, and therefore will not have to check every inch of the surface. This detector also has several significant drawbacks. For example, it cannot be used indoors if the electricity is just turned off. In addition, in places with high humidity, such as garages, baths, saunas, the device simply will not work. Also the device can not, will detect the wiring if the wall consists of a metallic material.
There is one more budget option, a detector for detecting hidden wiring. This detector works on the principle of an electromagnetic pulse, which allows you to find the position of the wiring with great accuracy. It can fix the location of even the wiring, which has a load of only 1 kW, that is, it is able to recognize the presence of the cable even in the off state. Detector actually reacts to the metal, which is part of the wiring, but this option is not always on hand when checking.
In private homes that are built of wood, the detector will work well. If the building is made of panel elements, which include steel rods, the detector will respond to any metal presence.
The most popular today is considered to be a combined detector for detecting hidden wiring. It allows you to find the location of the electrical system with high accuracy. In addition, you can select the function to work with this device. Thus, it is possible to determine cable breaks, the presence of non-ferrous metals, wood or plastic material. Combined detectors have only one major drawback - high cost.
How to choose a hidden wiring detector?
A variety of detectors for detecting hidden wiring is quite large in the modern construction market. Therefore, before you go shopping, you need to decide for what purposes it will be intended. For example, it can be used only once or repeatedly. Detector may be needed to detect a simple cable pattern or to search for all hidden parts in the wall of the room.
It is also worth taking into account its characteristics. We are talking about power, the depth of scanning the wall and the time of work. If you select the wrong type of device, you can simply skip some cable section, since the device is simply not designed for a sufficiently large scan depth.
Professional models of the device are used, as a rule, in enterprises where the depth of the cables can be quite large. Such a device will certainly detect wiring at any depth, but because of its high cost, it is simply not necessary for working in living conditions. If we are talking about checking the availability of wiring in a private house or apartment, a simple type that accurately indicates the location of the electrical network will do. The simplest type of detector that works when electricity is on is usually not very effective, but suitable for single use and save from injury and burns.
Hidden posting search system
As a rule, all hidden wiring detectors operate on the principle of electric field detection. Expensive models can detect such a field even when the state of electricity is off. The detector picks up the electric field and sends a signal that will indicate the location of the cable.
Before starting work the device is turned on using a special buttonlocated on the device. As a rule, immediately after switching on, he starts the calibration himself, for more accurate work in the future. At this time, you can not interfere with calibration or bring the device to the wall, where there is simply no wiring, but you can help if you install the device to the place where the cable passes.
After the calibration has ended, you can start working. The device is held over the entire surface of the wall. A wiring detection signal will arrive when the device detects a cable. As a rule, the time of such work depends on the quality of the detector model. As mentioned earlier, the detector can be used on large areas of the wall surfacewhile cheap models can only capture a signal from an electric field in the range of a few centimeters.
In addition, the operation of the device also depends on whether the cable is under voltage or not. Cheap models may simply not work on wet surfaces or in places with a thick layer of finishing material or simply show inaccurate results.
Detector detection of hidden wiring do it yourself
It goes without saying that buying a device for detecting hidden wiring is much easier, but if it is be used only at the amateur level, then the device that can be made simply do it yourself is he can work only on cable holding places, which are energized and the accuracy of the indicators will not be as high. But the device is suitable if you just need to make a hole for the picture and make sure that there is no cable in the wall.
There are a lot of schemes for creating your own detector on the Internet, but they are all built on the same principle. It is necessary:
- pick up the material;
- assemble the device.
In order to assemble the simplest concealed wiring detector, you need to find a switch ohmmeter and a conventional field effect transistor. All these parts can be purchased at any construction market at a reasonable price. You can also use the headset, which has a battery, in the device. In this case, the device will show the location of the wiring not only by deflecting the arrow, but also a characteristic signal will be heard. The phone is needed only for comfortable use of the device, and it has no effect on all other parameters.
Assembling all the necessary parts passes quickly enough. Need only connect an ohmmeter to a field effect transistor and start checking the wall for wiring. As a rule, if there is a cable and the device picks up the electromagnetic field, then the arrow simply deviates to the side in places where the power is greatest.
In the case of connecting the phone, the principle of operation does not change. Here the differences are that when searching for a cable, the device will emit a signal, which as it gets closer to the electromagnetic field will simply increase.
The whole principle of the self-made detector for detecting the wiring is based on the properties of the field-effect transistor.
As you can see, such a device is not particularly powerful and can only be used at a shallow depth of wiring. In addition, it will work only if there is tension. He usually suitable for domestic useBut if it is tested at the enterprise or a person is engaged in repair or construction work, then it is best to purchase a multi-detector. It may cost more, but it significantly simplifies the work and improves the accuracy of cable search.
Detector models for hidden wiring search
There is a wide variety of detectors on the market. The most popular and versatile are:
- Model LA-1010, designed to search for cables at a relatively shallow depth. It can also be used in the form of a level or laser pointer. Advantage in features that allow you to search for alternating voltage conductors, and also designs from wooden and metal material.
- model LA-1014. Suitable not only for detecting hidden wiring, but also allows you to find breaks in the system of cables, overlap lived or short circuit.
- S-Line model. designed to detect hidden wiring, as well as metal, wood and plasterboard structures at great depths. This model refers to building types. It has automatic calibration, as well as a durable and easy to use case.
- model TS-72. A simple type of detector that is used mainly in everyday life. It can detect wiring in the on and off state, as well as metal and wooden hidden structures.
Thanks to a variety of detectors for detecting hidden wiring, you can greatly simplify the work in construction, repair or just when installing an interior element when you need to punch wall. The device also allows to reduce the level of danger to human health when working with the mains.
