3.2.2. Live wires must not touch grounded parts or other phases; they must have a minimum length and be firmly connected to the main circuit. The wires must be single-core, multi-wire, with insulation corresponding to the voltage of the circuit being measured, their cross-section must correspond to the measured current value and be at least 2,5 mm2.

3.2.3. During the measurement, it is forbidden to touch the wires, devices.

4. Labor protection requirements at the end of work

4.1. Remove the posters from the electrical inputs of the main switchboard. Turn on both switches on the main switchboard. Using a batch switch on the distribution board, alternately turn on the working and backup electrical inputs. Using the readings of the RSShch voltmeter, make sure that there is voltage in all phases.

4.2. Clean the workplace and make notes about the work done in the inspection and prevention log.

4.3. Place protective clothing and personal protective equipment in a specially designated place.

4.4. Wash hands thoroughly with warm water and soap.

4.5. Any deficiencies in labor safety discovered during work must be reported to the immediate supervisor.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean.

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. ... >>

Video camera with a speed of 156,3 trillion. frames per second 18.03.2024

Canadian scientists presented their latest development - a SCARF (swept-coded aperture real-time femtophotography) camera capable of capturing images at a coding rate of 156,3 THz for each individual pixel. This is equivalent to 156,3 trillion frames per second. The camera promises to revolutionize the study of microevents that occur too quickly for current scientific sensors.

The research, led by Professor Jinyan Liang of Canada's National Institute of Scientific Research (INRS), has opened up new opportunities to study ultrafast phenomena such as shock wave mechanics and the development of medical solutions. The SCARF camera represents a bold step in the field of ultra-fast photography, taking an innovative approach to data capture and image processing.

The fundamental difference between SCARF and previous models is the use of a computational imaging modality that allows the capture of spatial information about light at different points in time. This approach greatly enhances the camera's capabilities, capturing data with unprecedented speed and accuracy.

The SCARF camera has already demonstrated its effectiveness by capturing ultra-fast events that were previously unobservable. It opens up new perspectives for scientific research and brings a new perspective to problems that require high-speed analysis and observation.

The SCARF camera represents a significant advance in ultra-fast photography, opening up new possibilities for studying micro-events and phenomena occurring at unimaginable speeds. Its development opens a new chapter in scientific research and can lead to new discoveries and technologies in various fields of science and technology.
