Now, thanks to the efforts of our Chinese brothers, various electronic devices are increasingly penetrating even into household wiring. These are various electronic calls at the front doors, Christmas lights and garlands, sockets and switches that are triggered by a television remote control, devices for extending the life of incandescent lamps (delay when turned on), photo sensors to turn on lighting, electronic transformers to power low-voltage halogen lamps, spotlights with motion sensors and more.

Energy-saving lamps, popular recently, inside their base have a simple electronic circuit with only two transistors. And fluorescent lamps, remember, those with roaring chokes and blinking when turned on? Now, instead of chokes, electronic ballast is used ...

IN Visiting the site i.electricianexp.com, one of the best teachers of the Gomel State Polytechnic College Sergey Aleksandrovich Nikulin, who kindly agreed to cover some of my questions.

1. Sergey, you have been working at a college (technical school) for about 10 years now. Has anything changed during this time? How has the educational process and student attitudes changed?

A college (technical school) is the next stage of education after school or a vocational school and, unfortunately, in recent years, applicants who come to us have a low general level of knowledge, learning ability and desire to study. The capabilities of many of them do not allow them to master the specialty "electrician", in my opinion, quite complicated. But we have no other contingent, and therefore, we are teaching “untrained” ...

Who deceives a consumer or an electricity supplier, or how suppliers make money for us in excess of the electricity consumed.

I think most of us fell into such a situation when representatives from electrical household organizations came to allegedly check electricity meters, but at the same time, they offered their services, illegal, of course: “wind the meter back” in exchange for the nth amount, and the difference is false electricity to pay on receipt, citing new evidence.

So, about 5 years ago there was a case. Electricians came and offered their services. I figured, well, it seems to be profitable, and then there were problems with money ...

Quite often you have to observe the work of electricians, who, how and with what tool works. And sometimes you see a woe-electrician with a tool that can only, except that, hammer nails and poke around the walls ... After all, electricians are the intelligentsia among builders, white bone, so to speak ...

In this article, we will try to “assemble” an electrician’s suitcase, which we will equip with the most necessary electric installation tool that every self-respecting electrician uses in everyday practice.

So, the choice of an electrical installation tool for work is purely individual, but there is a universal set that is necessary for daily work. The following tools can be safely added to this set ...

What awaits you when getting an energy education.

In order to become an energy engineer, one must spend five years in the walls of his native university. If you do not know who you want to be in the future, or your parents cannot decide on the choice of your profession.

I want to give some advice. Do not panic at economists, programmers, and others of this kind.There are not so many energy faculties in our big country, economists at every turn.

And now, if you still decide to choose this particular faculty, then I will tell you a little how the training in this specialty goes ...

An electrician without power tools, this is not an electrician. After all, no matter what knowledge you might have, it is impossible to strip the wire, tighten the contact, measure electrical parameters, etc. without the appropriate tools. This is what every electrician should have his own and with him, as they say without a tool as without hands.

There is a huge amount of all kinds of tools, both for a specific purpose and all kinds of species.

Perhaps I think that you completely agree with me that having in your house a lot of any various things, you usually have to use only a small part of them, namely the most necessary. So in an electrician, you can carry many tools in a bag, although in practice only some of them are constantly used. This is the electrician’s tool, the main set ...

An article on how to choose a professional electrician.

If you fall into pessimism, and from its "heights" look at your apartment, the picture, I tell you, seems joyless. It turns out that our apartment is an endless source of disasters.

Let's start with the smallest - you can fall out of the window (if you look through the eyes of a pessimist, it will be obvious), from the balcony you can fall. The bathroom is just a crowd of disasters. The toilet is clogged, the taps are leaking, the risers are breaking through, as a result, the neighbors are drowning. But the worst danger is the wiring ...

First, a little about yourself. I am an electrician by profession. He worked for seven years in the housing office. We have such an ominous organization. Now the specifics of my work are a little different, but, nevertheless, questions on the topic "a real electrician's knife" still concern me. So about the specifics. That is, about what makes the situation unique.

Knives are different. Electricians are also different. I write about those electricians (strictly speaking - electricians) who work with a voltage of 220/380 volts with networks of 200 amperes or less. Those. Typical household and zheksky fitters. I won’t lie about other electricians - there’s another story. So here. It’s unlikely that anyone will be very interested in hearing about the installers themselves and the housing office, but reading the super-knife of an electrician can be fun ...
