For those who often spend their holidays outside the city or live in the countryside, the problem of constant voltage drops in the power grid has long been known. She is very annoying because often leads to failure of both lighting and large and expensive appliances such as refrigerators, microwave ovens, air conditioners, etc.

There are many ways to deal with the unsatisfactory quality of the voltage in the mains, but probably the easiest is to install a voltage stabilizer. Such stabilizers are common house (high power) and local, i.e. low power for a specific device. If you have enough money, then an all-round stabilizer is preferable, because It protects your entire home, not just a specific appliance.

The first thing to do before choosing a stabilizer is to determine its power. Ideally, it should be 30 percent higher than the total power of all your electrical appliances ...

In previous articles, we looked at how to automate the process of starting gasoline diesel or gas generators. Generators are most often placed indoors. One of the important, and for someone rather complicated moments of installation of mini-power plants, is the problem of exhaust gas exhaust. In this article, we will demonstrate step-by-step how to remove exhaust gases from the generator.

So what we have. Generator gasoline KAMA (KIPOR) KGE 6500 E. As already noted, a very successful model. Value for money is just super))). Corrugation. As a corrugation we use a bellows to connect hot water. As practice shows, three years of successful work are provided, the corrugation easily tolerates high temperatures and vibration of the generator. The paste is a sealant. In this case, asbestos-cement paste was used ...

The causes of energy losses in overhead lines and ways to deal with them, based on practical experience.

Probably, everyone who has a house in the village, lives in the private sector in the city or builds his own house, over time, will face the problem of instability of the electricity network. This is expressed in sharp surges, problems of protection of electrical appliances during thunderstorms, long periods of very high or very low voltage in the mains.

Many of these problems are associated with the features of overhead electric lines, others, with the failure to comply with the elementary rules for laying lines and their maintenance. Unfortunately, in our country, the slogan: "Saving the drowning people is the work of the drowning people themselves" is being increasingly implemented. Therefore, we will try to consider these problems and how to solve them in more detail. Where do the losses come from in electrical networks? ...

When installing and arranging the lighting of residential premises, the uniformity of lighting is always in the first place for the consumer. That is why spotlights, LED strips and neon light tubes have become so popular today - their light is not concentrated at one point, does not hurt the eyes and eliminates the appearance of shaded areas.

But with all this, well-known to all of us chandeliers, located on the ceiling in the center of the room, have not lost their positions. On the contrary: the variety of forms and design designs of modern chandeliers is simply amazing.

And, in the end, the need for general lighting of the rooms has not yet been canceled, and a more successful and beautiful solution to this issue than a chandelier has not yet been invented. However, the installation of chandeliers has a number of specific features, which we will try to talk about ...

There was an idea to make the swing gates yourself, as usual because of laziness. No wonder they say "laziness is the engine of progress." I decided to equip my garage swing gates with automation. The main issue arose with the drive.

When I found out how much what they put, it was a shock. And I’ll tell you why. If you pay 300 euros for two drives, well, excuse me, for what? Since I myself am engaged in satellite television, I decided to think a little bit unconventionally and cross “a camel with a rhino”.

As you know, in the old rotary systems of satellite dishes, a worm gear motor was used to extend the rod that drives the antenna. The principle of operation is the same as in the standard swing gate operator. Moreover, it seems to me that it even has its advantages. The drive needs 220V, and this one is powered through a transformer with a constant voltage of 36V ...

One of the advantages of infrared heaters is the ability to work with various control devices. First of all, these are various thermostats that maintain a given temperature.

It is also possible to connect programmable control devices. With the help of such devices it is possible to perform a wide variety of tasks. For example, you can set the heater to turn on on individual days, and even hours. All of the mentioned automatic devices can also be used to control the heating of an infrared warm floor.

Mechanical thermostats for infrared heaters are produced by many companies, while their parameters differ slightly. Almost all are designed for installation on a wall, the type of installation of the invoice or mortise, which allows you to use them with any type of wiring ...

From a natural point of view, traditional heating systems do not work properly. First, the air heats up, and then everything else. Under natural conditions, everything happens the other way around.

The natural source of heat on Earth is the sun. The sun's rays have a very wide spectrum, but it is its infrared component that heats the Earth, people, plants and all objects, and from them the air heats up and creates comfortable conditions for human life.

It is by this principle that infrared heaters work. The air for infrared radiation is absolutely transparent, therefore infrared rays freely reach heated surfaces and objects.

The intensity of thermal radiation depends on the wavelength of infrared radiation: short-wave rays are obtained at a temperature of the radiating body above 750 ° C ...

In the process of wiring, very often you hear the following question: what to choose - a residual current device (RCD) or a differential circuit breaker? So let's find out what is actually better. Differential automatic machine or RCD.

I will tell you definitely. The correct answer to this question does not exist, because The choice between an RCD and a differential automaton depends on numerous factors.

But still, I’ll try to explain and give you the opportunity to make a choice on my own with examples.

Point 1. Free space in the shield. First of all, you need to determine if there is free space on the DIN rail in your apartment panel ...

According to the classification adopted in the PUE, the bathroom in any apartment is, if not particularly dangerous, at least a room with increased danger.This means that the likelihood that a person will be shocked in the bathroom is high, and the consequences in the event of such a shock will be more severe.

Higher danger implies greater responsibility and requires us to take additional safety measures when installing and installing the electrical wiring of the bathroom. The following measures are recommended for rooms with increased danger: the use of protective grounding, the introduction of a third, protective conductor PE, the use of devices for protection against leakage currents - RCDs or differential circuit breakers.

For bathrooms, both measures are mandatory. Many also consider the requirement for a hidden wiring device in the bathroom ...

When planning lighting, we want it to be even. Of course, we want the light not to be too bright, so that it does not cut eyes, does not distort colors, and does not interfere with perceiving the surrounding reality.

All problems are eliminated using spotlights. High-quality and even lighting of the working area of ​​the kitchen, soft and soothing light in the recreation area, lack of darkness and comfort for the eyes - all this is fully possible using this special type of fixtures.

The popularity of spotlights is constantly growing, their diversity is becoming increasingly widespread, and each electrician already has his own specific set of knowledge and skills that help him quickly and efficiently install the so-called "lighting points". Spotlights are recessed fixtures. This means that they can only be installed on hollow structures ...

Various electronic remote lighting switches can be divided into two large classes of infrared and radio-controlled. What are the advantages and disadvantages of these devices, why are they needed if the light can be turned on with a simple switch?

Here you can recall how already in time immemorial it was necessary to approach the TV and use the handle to switch channels, and sometimes even pliers. Do you remember? Perhaps the first devices equipped with remote control, just became the TVs.

A bit later TVs came with VCRs, DVD players, and all of them were equipped with infrared remote controls. Such a number of infrared remote controls has led some companies to develop switches, dimmers and sockets controlled by infrared rays ...

During repair and construction work, one cannot do without a power tool, the quality of the repair as a whole will depend on its quality. Therefore, it is very important to choose the right tool, which will be discussed further.

Today it is impossible to imagine apartment repair without using a power tool. Arriving at any specialized store, you can appreciate the huge variety of types of power tools, where each device has its own purpose and technical characteristics. Choosing a power tool is not an easy task. It’s not enough to understand that for drilling walls you need a drill or punch, you also need to understand the technical characteristics and capabilities of the tool. First of all, you need to determine for yourself which tool you need - professional or non-professional ...
