In the world of technology AI is on the tip of everyone's tongue these days. AI being a major trend in tech development for a while, AI appearing more and more like one of the most demands in areas of expertise. Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. Specific applications of AI include expert systems, natural language processing, speech recognition, and machine vision. Most artificial intelligence systems have the ability to learn, which allows improving their performance over time. The recent research on AI tools, including machine learning, deep learning, and predictive analysis intended toward increasing the planning, learning, reasoning, thinking, and action-taking ability. As AI is becoming part of our life, it will affect our future nearly. Here I am showing some of the scenarios that can be happen in near future: Transportation: Although it could take a decade or more to happen, autonomous cars will...

The substation is combined with many electrical devices like transformers, isolators, electric lines, etc. Electrical devices are sensitive and have to protect carefully. Usually, the protector of the substation is stone. Isn't it surprising? Have you thought it should be more advanced? In the world of technology why stone is used as a protector? You will be surprised to know the fact that stone is the perfect natural protector. Today I will explain this topic to you. The most important part is the ground potential rise (GPR)  The maximum electrical potential that a substation grounding grid may attain relative to a distant grounding point assumed to be at the potential of remote earth. This voltage GPR is equal to the maximum greed current times the grid resistance. Step voltage: It is defined as the maximum potential difference that exists between the feet when a fault current flows in the body. A particular case of step voltage is the transferred voltage where a voltage is trans...

We often see transformers in our way almost every day, everywhere. We all might have noticed that there is something written in the transformer like Dny11. But we don't know what does it mean? We can guess that the numbers on the transformer windings show the turns ratio between windings. But by reading this article we might confirm this guess.  The first letter D shows that the primary winding configuration is in delta connection. The second small letter n shows that it has the neutral point and the small y shows that it is star connected. Letter 11 shows the phase difference between the primary and secondary connection according to clock configuration. When the clock hands are between 11 and 12 the angle between them is 30 degrees. So, Dny11 means  D- Primary winding in delta connection ny-Secondary winding in star connection with a neutral point 11- There is a phase angle difference of 30 degrees between the primary and secondary line voltages. The secondary line voltage la...
