Let's imagine a workshop of a certain manufacturing enterprise where people work, in which there are machines, various equipment is installed and configured there, a lighting system is functioning, etc. This enterprise produces something, it has contractors, customers waiting for deliveries. But suddenly, in one of the electrical connections, a conduction disturbance suddenly occurs. What can be the result? But this could have been avoided by carrying out preventive thermal imaging control of numerous electrical components at the enterprise in a timely manner. The bottom line is that a faulty component ...

For the purpose of electrical insulation of conductors, electrical insulating materials, dielectrics, are used. These materials have extremely low conductivity and high electrical strength, so they are well suited for this kind of application. There are organic and inorganic electrical insulating materials. Organic, unlike inorganic, contain carbon. As for inorganic dielectrics, they have better temperature characteristics. According to the method of their production, electrical insulating materials are natural (natural) and synthetic. Synthetic materials are often preferred because, thanks to the vast possibilities of the modern chemical industry, there are opportunities to create materials ...

In nature, there is a special structural modification of carbon, in which the graphene plane (a layer of carbon one atom thick) is rolled into a tube. Such carbon tubes, up to several nanometers in diameter, can reach several centimeters in length; and in principle it is possible to connect individual tubes to each other and obtain even more extended structures from them. To date, there are hundreds of methods for the synthesis of carbon nanotubes, which make it possible to obtain structures of various lengths, diameters, wall thicknesses, imperfections, etc. Carbon nanotubes are single-walled and multi-walled; they find application in various fields ...

A switchgear is an electrical installation designed to receive and distribute electrical energy of a specific voltage class. Such an installation includes switching devices, connecting buses, auxiliary devices for relay protection and automation, as well as measuring and accounting tools. There are switchgears assembled from standard unified cells of a high degree of readiness; such switchgears are called complete switchgears. They occupy a small area under them, so they are well suited for indoor installation. The usual complete switchgear is a metal box, divided inside into four compartments, located one above the other ...

Imagine this situation: we are driving a car and suddenly we begin to smell a sharp smell of gasoline. We stop and see that a puddle quickly forms under the car. We have discovered a malfunction that needs to be fixed urgently before it gets worse. And we can already say for sure that in this case the costs of time, effort and material resources are inevitable. Of course, if the malfunction has matured over a long period of time, then timely predictive diagnostics would be very helpfull: the root cause could be detected by the first signs of an emerging malfunction, and, resorting to professional maintenance, an accident could be prevented ...

Like any other electrical equipment installed in a substation, power transformers not least need reliable electrical insulation. And if we talk specifically about transformers, then they can clearly separate the internal insulation and external insulation. External insulation (air gaps). The outer insulation of a transformer mainly includes air gaps. In practice, these are all possible gaps between the external conductive parts of the transformer, one way or another connected with the inputs. The longitudinal insulation of a winding is the insulation between adjacent layers of its turns. It can have different dimensions and be made in the form of various structures, determined by lightning surges. ...
