The troubleshooting algorithm helps to quickly find the cause when the RCD is triggered.

For reliable protection, do not forget to monthly check the performance of the RCD using the "Test".

Strength - receivers of electrical energy: lamps, electric kettle, washing machine, TV, refrigerator, electric stove, heated floor, etc.

Feed lines - electrical wiring and junction boxes, switches and sockets.

Load power circuit - the entire supply section is considered, including both the load and the supply lines.

Troubleshooting algorithm for RCD tripping

Note:

If the RCD does not turn on when the machines are turned off, this means that there is a leak in the insulation of the shield wires or the RCD is faulty.

If the RCD does not turn on when the entire load is disconnected, this means that there is a leak in the supply lines.

If the RCD trips when all the load power circuits are turned on, this means that the RCD is not correctly selected for the leakage current.

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. ... >>
