Elektroblog
On our electroblog we will gradually try to explain the basic electrician topics as simply as possible and also point out common mischiefs or other delicacies that we sometimes encounter on construction sites.
Although in the electroblog you can find not only electrical theory but also practical experience, the electroblog is not intended as a guide for electrician beginners. Always remember that only an experienced electrician is allowed to work with electricity.
For the layman uninitiated in electricity...
- Effects of electric current on the human body.
- Electrolytic breakdown of blood by direct current.
- Can I install electrical wiring by myself?
- Self-help electricity - lighting switches and why we have so many different types.
- Self-help electricity - sockets.
- Possible risks of careless LED installation.
- Resistance of equipment to the effects of water and dust, or what IP rating actually is.
- Why a swallow sitting on a wire doesn't get a flake, or an introduction to electrical capacity.
- Why isn't my floor or radiator heating?
A little electrical theory... or yay back to school
- Ohm's and Kirchhoff's laws.
- Types of electrical networks - what do the abbreviations TN-C, TN-S, TN-C-S, TT and IT stand for.
- Electrical power and input in a 1f system, efficiency and power factor.
- Electrical power and power input in a 3f system, star and triangle.
- Motors - generation and transmission of spinning magnetic field.
- Motors - reversal - change in direction of rotation.
- Motors - switching star/triangle motor.
- Electrical circuits with resistors - series and parallel wiring.
- Electrical circuits with resistors - triangle/star transfiguration and vice versa.
- Electrical circuits with inductors (coil) - series and parallel wiring.
- Electrical circuits with capacitors (capacitors) - series and parallel wiring.
- Overvoltage in an electrical network and its causes.
For more experienced sparkies......
- Why it may not be a good idea to plug in more and more extension cords.
- Why it's not a good idea to get a grounding sheet for your old house.
- Does every light in houses and apartments have to be on a separate residual current device?
- Why is there unwanted equipping of the residual current device?
- Why must the point of distribution be earthed or how an interrupted PEN can be troublesome.
- Why it is not a good idea to make a five-pin four-pin and why it is better not to touch it at all.
- How to lose 20k CZK on a bill thanks to unprofessional intervention in the electrical distribution board.
- How to protect the wiring against possible overvoltage.
- Surge protectors SPD and general principles of their correct installation
