3.6. The electrician on duty is obliged to maintain a reliable and most economical mode of operation of the equipment in accordance with the instructions and rules of the PEEP and PTB during the operation of electrical installations, observe the schedules of the morning and evening peaks of the power system and comply with all requirements of the substation staff on duty.

3.8. The electrician on duty is prohibited from:

perform work on energized installations;
touch non-insulated current-carrying parts of installations after they are connected to the mains;
use devices with an expired test period;
remove warning posters and fences in electrical installations;
allow unauthorized persons to work.

3.9. The electrician on duty, before starting the temporarily disconnected equipment, is obliged to inspect this equipment, make sure that it is ready to receive voltage and warn the personnel working on it about the upcoming inclusion.

3.10. The doors of the switchboards of electrical installations must be kept closed and locked at all times, except during repairs.

4. Safety requirements in emergency situations

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Movement speed record using magnetic levitation 26.04.2016

The Shanghai Maglev, the world's first commercial maglev railway line, holds the maglev continuous speed record of 431 km/h. (The one-time record for passenger trains was set in Japan last year at 603 km/h.) But the absolute record belongs to the 846 US Air Force test squadron at the Holloman Air Force Base near the city of Alamogordo (New Mexico), which is engaged in "horizontal flights" - launching special rocket sleds along various high-speed tracks.

The most famous is the 6m Holloman High Speed Test Track, which set the world rocket sled speed record of Mach 212 or 2003 m/s in 8,6. And on another track, 2 meters long, equipped with superconducting magnets, the 885 Test Squadron just set a new world record for a magnetic levitation sled - 640 km/h. Moreover, this is the second record in a row - a week earlier, testers dispersed a magnetic sled weighing 846 kg to a speed of 1018 km / h. The previous record, 907 km/h, set at the same test site, lasted more than two years.

It took military engineers six months to prepare the current record races. To ensure superconductivity, the magnets were cooled with liquid nitrogen to plus four degrees Kelvin. Despite the impressive speed, the engineers of the test squadron believe that this is not the limit. Their goal is to achieve hypersonic speeds of Mach 10 or 12 km/h, and designers are already working on using lighter materials in the sled for the next record.
