6.3.15. Outdoor lighting installations can be powered directly from transformer substations, distribution points and input distribution devices (ASU).

6.3.16. As a rule, independent lines should be laid to power street lighting fixtures, as well as outdoor lighting of industrial enterprises.

It is allowed to power the luminaires from the phase and common neutral wires of the overhead electrical network of the city, settlement, industrial enterprise additionally laid for this.

6.3.17. Lighting installations of urban transport and pedestrian tunnels, lighting installations of streets, roads and squares of category A in terms of reliability of power supply belong to the second category, the rest of the outdoor lighting installations - to the third category.

6.3.18. Power supply for lighting fixtures for the territories of microdistricts should be carried out directly from power points for outdoor lighting or from street lighting networks passing nearby (excluding networks of category A streets), depending on the operation system adopted in the settlement. Lamps for outdoor lighting of the territories of kindergartens, secondary schools, boarding schools, hospitals, hospitals, sanatoriums, boarding houses, rest houses, pioneer camps can be powered both from the input devices of these buildings or transformer substations, and from the nearest distribution networks of outdoor lighting, provided compliance with the requirements of clause 6.5.27.

6.3.19. Lighting of open technological installations, open work sites, open flyovers, warehouses and other open facilities at industrial buildings can be powered from the internal lighting networks of the buildings to which these objects belong.

6.3.20. It is recommended to feed security lighting, as a rule, along independent lines.

6.3.21. The supply of lighting fixtures at entrances to fire-fighting water sources (hydrants, reservoirs, etc.) should be carried out from the phases of the night mode of the outdoor lighting network.

6.3.22. Luminaires installed at the entrances to buildings are recommended to be connected to a group network of internal lighting and, first of all, to a network of safety lighting or evacuation lighting, which are switched on simultaneously with working lighting.

6.3.23. In outdoor lighting installations, luminaires with discharge sources must have individual reactive power compensation. The power factor must be at least 0,85.

6.3.24. When using searchlights with discharge light sources, group compensation of reactive power is allowed.

With group compensation, it is necessary to ensure that the compensating devices are turned off simultaneously with the shutdown of the installations compensated by them.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Mobile phone Ericsson K850i 12.07.2007

Sony Ericsson has officially introduced a new mobile phone K850i, which allows you to take pictures with a resolution of 5 megapixels, including using the built-in flash and burst mode (BestPic).

Like previous Sony Ericsson camera phones, the new product uses the same Cybershot trademark as Sony's digital cameras. An intuitive interface ensures simplicity and ease of operation, both when shooting and when viewing the resulting image.
