Often, before carrying out any excavation work, or even for the purpose of servicing a cable laid underground, it is necessary to find this cable. Agree, it will be very annoying to damage the cable laid underground, for example by hooking it with an excavator bucket or accidentally drilling it. In order to avoid such incidents, you must first obtain reliable information about the location of the cable underground, the same applies to underground communication pipelines.

If the information about the location of the cable laid underground is not reliable or insufficiently accurate, then unnecessary costs and errors are inevitable, and such errors are sometimes fraught with dire consequences for health and even for people's lives. The condition of the underground cables can be estimated by the route locators, but sometimes it is necessary to localize the cable underground to continue ...

Nibbling of hands, especially wounds, scratches during their contact with water when washing hands does not pose a danger to humans. But light and seemingly harmless tingling can instantly turn into a strong electric shock. Tingling can be considered as an alarm signal, namely, to search for a source of current leakage - a damaged electrical appliance or go to a damaged section of home wiring.

In most cases, the cause of tingling is damage or improper connection to the electrical network of a household appliance, which in the process of operation is connected to water, pipelines of the apartment (house). This is primarily a washing machine, storage water heater (boiler), instantaneous water heater, dishwasher. When installing electrical wiring, it is recommended to pay special attention to ...

The term “sensor” itself means a mechanism designed to measure a parameter in order to further process the measurement result. The sensor circuit generates a signal in a convenient form for transmission, then the signal is converted, processed or stored. Without sensors in some modern areas of industry, and in many equipment of various kinds, just can not do.

Electronics today makes it possible to manufacture electronic sensors capable of monitoring processes by several parameters at once, which greatly expands the possibilities for constructing complex measuring and actuating devices. The sensor necessarily contains in its design a sensitive element and often a converter part. The main characteristics of electronic sensors are their sensitivity and measurement error. To date, analog and digital sensors ...

The life of a modern person is connected with the operation of a large number of various equipment, the work of which is often monitored remotely using various types of signaling. Among them, information on the onset of a fire at critical industrial facilities and inside multi-story buildings with a large number of people is given crucial importance.

Its main task is to ensure that, at the first signs of a fire, information is quickly transferred to the duty service, which is able to quickly arrive at the scene and take emergency measures to extinguish the fire, and prevent its spread. Additional tasks of fire alarm systemsmay beremote activation of pre-arranged fire extinguishing means - various types of fire extinguishers, unlocking ...

Using electric energy, the owner of any building is interested in ensuring maximum safety during long-term operation with a high degree of reliability. These issues are especially acute in houses built of combustible materials: wood, timber and SIW panels. The latest designs have long been widely used in North America, Canada, and the Scandinavian countries. A few decades ago, they began to be built in the CIS countries.

SIP, for reference, denotes a panel with a structure of insulating materials, when a layer of expanded polystyrene is placed between two plates of OSB, which we commonly call foam. This filler may burn well, as it was in the Lame Horse building in Perm, or may not support combustion with a self-extinguishing structure that uses antipyrine additives. The quality of both grades of material can be checked ...

Today, robotics is conquering ever-larger industries and is increasingly being introduced into various spheres of human life. And if earlier robots could fulfill the role of man, replacing him in factories, which often require uniform actions in the conveyor production, for example, in the manufacture of automobiles, now the time has come when robots are able to be in every house to help people solve urgent tasks, and help save our time and effort.

Household robots designed to help a person in his daily life are gaining more and more popularity, which is not at all surprising, because the variety of robots is growing every year. Already today it includes vacuum cleaners, lawn mowers, window washers, pool cleaners, and even snow-removing robots. By the way, back in 2007, Bill Gates drew attention to the significant potential ...

When installing a socket or other elements of electrical wiring, the need to connect a cable in a junction box, the question arises of how to determine where which wire is from the three available. Where the phase wire is located, as a rule, it is not difficult to determine - just use an indicator screwdriver for this. The question then becomes: where is the working conductor from the remaining two wires, and where is the protective ground conductor.

If the conductors are not marked, that is, they do not have corresponding tags indicating where which wire is, then for many this becomes a problem. In this case, it is necessary to determine exactly where which wire is, since in case of an erroneous connection, negative consequences are possible - short circuit or electric shock. Below we will try to answer the question of how to determine the ground wire in home wiring ...

In addition to providing reliable power to household appliances, it is very important that home wiring is safe to operate. Safety consists, first of all, in preventing electric shock. That is, home wiring should be performed in such a way as to exclude the possible impact of electric current on a person.

The main methods of protecting electrical wiring is grounding the electrical wiring, as well as the use of appropriate protective devices - residual current circuit breakers, differential machines. In this article, we will consider the question of how to ground the home wiring. Before doing an individual grounding of the wiring, you need to figure out whether it is necessary at all. Often people make grounding in the house, arguing their actions ...
