And how do you want to completely protect your home from any troubles.

We put reliable locks and strong doors from burglars, fire and security alarms, ask neighbors to look after the house if we leave somewhere.

There are no trifles on security. And electrical safety is one of the guarantors of the safety of your property and your life ...

The most rational, in terms of economy, is the use of a UPS uninterruptible power supply, where the battery is used as the energy source.

Today, in the Uninterruptible Power Supply-UPS market, there are 3 main types of devices - on-line, off-line and line-interactive UPS. In this short article we will try to figure out what is the difference between these devices, which one is better, the advantages and disadvantages of each of the devices.

Before we begin to analyze the advantages and disadvantages of the UPS, you must determine the degree and importance of the equipment that will power the UPS. In order to determine which device you need, answer a few questions that will facilitate the further selection of the UPS ...

The problem with electricity in our homes has become, unfortunately, already commonplace. They can turn off electricity quite unexpectedly, without any warning. And imagine such a situation ... Winter. On the street, frost is under - 20, you go home, the snow crunches under your feet ... Come home, and there ... it's dark, the house is cool, uncomfortable ...

In this short article we will try to figure out how to avoid situations, so as not to be left without heat, so that your boiler functions at five plus.

If you are the lucky owners of a private house, to ensure uninterrupted power to the heating system, you can between the UPS on batteries and the gas or diesel generator. You decide. Consider the advantages and disadvantages of these alternative sources of electrical energy for autonomous power supply at home.Let's start with Uninterruptible Power Supply (UPS) ...

Temperature regulators - what is it? The name itself already shows that this is a device, a mechanism by which you can adjust the temperature.

In everyday life, temperature controllers are found in almost all devices where one way or another it is necessary to regulate or maintain the temperature within specified limits. In this article we will try to figure out where, how and which temperature controllers are used.

The most common are three types of temperature controllers: electronic, electromechanical, mechanical. All three types of temperature regulators, one way or another intersect each other, in terms of design. Let's consider each type of temperature regulators in more detail ...

The power electrical equipment of the house includes pumps, fans, compressors, mechanisms for opening gates and other mechanisms equipped with electric motors.

If the house is powered by a three-phase circuit, then it is advisable to use three-phase power (and thermal) equipment. To drive such mechanisms with three-phase power, an asynchronous three-phase motor is most often used.

Information about the engine is indicated in its passport (in the documentation and on a metal plate attached to the housing). Nominal values ​​are given here, i.e.those for which the engine is designed during its normal operation at the maximum permissible load ...

Overloads in electric Networks lead to the heating of wires and cables above their permissible temperature in terms of safety and reliability.

For wires and cables with rubber and plastic insulation, PUEs set the maximum permissible heating temperature + 65 ° C for a long current load. Permissible current loads depend on the cross section of the conductor, its design, cooling conditions and the laying method.

When overloaded in electric of the network aging of the insulation of conductors occurs: the rubber dries, crackes and crumbles, the plastic insulation and the shell melt and soften, the paper braid is charred ...

It should be noted right away that all wiring to the meter is under the strict control of Energonadzor. This suggests that, say, the owner of the house will not mount this part of the wiring himself, except as an exception, at the appropriate stage of construction, if the owner knows how to connect the input cable (wire) to the input breaker inside the house.

But connecting to power supply systems is definitely prohibited. At the same time, this information will help you have an idea:

1. How the employees you hire adhere to established rules;

2. What preparatory work will have to be done;

3. What materials, types of basic work will be required and, accordingly, how much will it cost ...

An article on how to choose the right section of a wire or cable

During electrical work, namely, at the stage of laying wires, cables, “Especially Advanced” customers ask why we lay, for example, sockets, a cable with a cross section of 2.5 mm square, when 1.5 mm square is enough, based on power consumption ... In this article we will try to deal with the cross-section of wires laid for various consumers.

So, on how correctly you select the cross-section of the laid wires, the further performance of consumers depends in many respects.

Wiring in a house, cottage or apartment begins with an input cable. The main load that is in the house lies on this very cable. In order to find out what section the input cable is needed, we need to count all the electrical appliances that can work in the house ...
