Before installing a two-tariff electricity meter, everyone wonders how profitable it will be, and whether it will be profitable at all? In fact, not everyone will experience the economic effect of installing a two-rate meter. For some, the benefit will immediately become apparent, for someone it will appear after a while. Let’s figure out how things really are with two-tariff electricity meters, and in which cases the transition is not at all advisable, and it’s more profitable to leave a single-rate meter.

Continuously, throughout the day, everywhere there is a dynamics of electricity consumption, and this applies both to apartment buildings of megacities, and to private houses. Most people sleep at night, and during the period from midnight to 5 a.m., electricity consumption is minimal. Waking up in the morning, getting ready for work, people begin to use electrical appliances ...

When designing a lighting system, after repair or construction of an office or residential premises, it is necessary to make calculations so that there is enough light. It does not matter whether conventional incandescent lamps, compact fluorescent lamps or LED lamps are used, it is required to obtain such a luminous flux as a result so that it provides comfortable conditions for a person.

If we are talking about replacing incandescent lamps with LED ones, then in principle there is no problem in choosing LED lamps for the corresponding luminous flux, there are tables for this, since the average luminous flux for typical incandescent lamps for each specific rating is known, and the luminous flux of LED lamps can also be easily recognized simply by reading the inscription on the package.But what to do if you want to get a modern lighting system based on LEDs ...

The owners are trying to create most modern living quarters with perfectly aligned walls, floors and ceilings without unnecessary protrusions, and all electrical communications are hidden inside building structures. This allows you to create a unique design, restricts access to electrical wiring, but complicates its inspection and maintenance.

The technology for installing hidden electrical wiring can be performed in various ways, which are constantly being improved with any method of building construction. For each particular case, choose the best option that meets two basic requirements: reliability and safe operation. The installation cost should also be taken into account, but it should not be considered at the time of wiring, but should be considered in conjunction with ensuring the possibility of a long, safe operation, excluding the occurrence ...

Every modern person, one way or another, uses electronic mobile devices in everyday life. These devices include both mobile phones, smartphones, tablets, laptops, players, and portable medical equipment such as blood glucose meters, and complex vital devices and prostheses that require autonomous power.

Obviously, the use of batteries today is very important. Not every gadget is conveniently plugged into an outlet every time, not everywhere the outlet is at hand, and sometimes it is just necessary to have an autonomous power supply, in particular in the field, the same flashlights are an ordinary but vivid example. Thus, the main power source for portable devices is the battery.If there is no battery, then the device simply will not be able to work, and cannot be used for its intended purpose. As a result, our life is gradually filling ...

The microwave today occupies an honorable first place among kitchen appliances. And this is not at all surprising, because with the help of a microwave oven you can both heat and defrost, and prepare various dishes. But more often than not, we warm it up in it. In a matter of minutes, you can warm up a good bowl of soup or pasta with grated cheese on top. In short, a useful thing is a microwave.

According to legend, the inventor of the microwave, American engineer Percy Spencer, working in his forties with magnetrons for radars, once noticed how, during one of the experiments, the microwave radiation of the magnetron so heated the chocolate in his pocket that the chocolate melted and burned Spencer. So Spencer came up with the idea of ​​creating a microwave oven, and already in 1947, the first Radarange microwave oven, designed to defrost food in canteens ...

If someone still believes that there is nothing better for connecting the wires than stripping their ends with a knife, twisting them, and wrapping them with electrical tape, then he is behind the times. Today, there are already plenty of alternative devices that greatly facilitate the process of connecting wires, and at the same time are quite reliable. Times of twisting will soon sink into oblivion, for they are replaced by a variety of terminals.

Why are the terminals good? How, for example, to connect an aluminum wire with a copper wire so that the connection is reliable and durable? It is absolutely impossible to twist copper with aluminum, because then a galvanic pair is formed, and corrosion will simply destroy the connection, it does not matter what size the current will pass through the twist, it will break down sooner or later, and if the current is greater, turn on and off the devices more often, then twisting resistance will increase faster, with time heating ...

The advent of home theaters greatly expanded the old possibilities of television. Now movies can be watched in remarkable quality and with excellent soundtrack. The modern home cinema market allows you to purchase a system for every taste, and the capabilities of these systems are associated only with the thickness of the consumer’s wallet and with his preferences.

In its original form, a home theater is a receiver and a set of speakers. It can play video and sound from both discs and flash drives, and even from video tapes. The connectors for connecting the receiver to the TV are different, so let's figure out how to connect the home theater to the TV in one case or another. For starters, speakers, speakers are connected to the receiver. There may be several speakers, depending on the model of the home theater, but there are at least six of them ...

When deciding on the power supply of a newly built building, its owner is faced with numerous tasks that need to be solved by technical and organizational methods. In this case, you should initially decide on the necessary number of phases required to power electrical appliances. Usually people are satisfied with a single-phase power supply, and a certain category selects a three-phase, guided by the tasks they face. When choosing a circuit, one should take into account its effect on the wiring design and operating conditions created by different systems.

There is a hope among individual homeowners that switching to three-phase power can increase the allowed power consumption and use electricity more intensively.However, this issue must be addressed in the sales organization ...
