Electrical installations

Do I need an electrical installation?

This is a question that no one asks. Because the answer is simple. Modern man is completely dependent on electricity - just imagine a day without electricity! But man is not its slave, but has made it his best assistant. Man is also thinking more and more about how to save electricity in order to protect the planet's resources.

The electrical installation supplies electricity and ensures people’s safety. It includes many modules and systems for electricity distribution and saving. An important part of it is the protection of wires from overcurrents and short circuits, which is one of the common causes of fire. Circuit breakers are intended to break the electrical circuit and eliminate the possible dangerous consequences of overcurrent or short circuit, but they do not protect people or consumers. This is provided by other devices and systems, such as residual current devices and cathodic arresters.

Lighting Control

Electrical installations also include lighting control systems, which are used for both convenience and energy saving. This is achieved with motion detectors or photosensitive elements that automatically turn the lights on and off. Other energy saving devices are the ones used for stairwells, which turn off the lights after a pre-set period of time, as well as dimmers which control the level of illumination depending on the user's wishes.

Lightning protection

Lightning protection systems can be of two types - active and passive. Passive systems include a lightning rod - a metal rod that is grounded and thus "leads" the lightning to the ground, protecting the building from direct damage. Modern lightning protection devices are the active receivers. They operate on the principle of anticipatory action and so lightning does not reach the ground. This method of lightning protection is more effective and is often used in large sites - stadiums, hypermarkets, airports, hotel complexes, etc.
