In these posts, I explain electrical engineering like the working of AC supply, circuit breakers, capacitors, inductors, control systems, Mosfet, thyristors, IGBT, inverters, DC supply, SMPS, power transmission, etc.
I will also cover power factors, reactive power, transformers like PT, SMPS transformer, open circuit current transformer, and also locomotive engine working concepts
The high-speed bullet trains can go very fast. It is due to specially designed rails, tunnels, aerodynamic design, distributed engines, VVVF, etc. I will also explain about tunnels, rails, distributed or invisible train engine, train turning at high speed etc.
How do high-speed Bullet Trains go so fast and work Read More »
Metal oxide varistor (MOV) finds use in many electrical and electronic equipment. I will explain in detail, that what is metal oxide varistor and how to use it.
I also will explain, from where the voltage spike comes in the electrical cccircuits with the help of various circuit diagrams.
What is Metal Oxide Varistor (MOV), and its use Read More »
The type of AC or DC motor used in a locomotive train engine depends on the technology available, and technical advantages. And it also depends on the cost of running the train.
I also will discuss, reason for the using AC or DC motor in the train engine.
Which Motor (AC, DC) is Used in a Train Engine and Why Read More »
I discuss, an arc fault detection device (AFDD) or arc fault circuit interrupter (AFCI). You also learn some functions in AFCI AFDD breaker like flame formation, electric current signature sensor, algorithm concept of measurement, a block diagram of AFDD, causes of arc fault, and types of arc faults.
What is AFCI or AFDD Breaker, and How it works Read More »
I will explain, AC or DC, which is more dangerous in this post. There are many factors that decide the intensity of electric shock on the human body. These other factors also play a very important role in addition to DC or dangerous AC frequency.
I will explain all these like AC or DC, which is more dangerous frequency to the human body in this post. Further, I also will discuss in detail the other factors affecting the intensity of electrical shock to the human body.
AC or DC current, which is More Dangerous to the human body Read More »
In this post, learn, that what is an electrical relay, and how it works. What are “NO” and “NC” contacts, contact working and the applications of the relay. I will also discuss the problem of low voltage in relay and voltage currentr rating of the relay.
