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
You will learn, what is a potential transformer, and also its applications. specifications and the test conducted on the potential transformer (PT). I will tell some extra knowledge as per my experience. I will also explain about capacitove voltage transforme ralso.

In this post I will explain, that why 30mA type RCCB breaker is used in the home and tripping time of the 30 mA RCCB. And if 30mA is not possible. Then how to use 300mA type RCCB breaker.
I will explain. where to use higher rating type RCCB breaker. Protection concept and as usual, I will share some extra knowledge as per my experience.

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.
