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
In this post, I explain, how to use a CT transformer (current transformer) with an open circuit secondary under certain conditions with a few examples. I will also explain, why high voltage comes in an open circuit, voltage limiting factors, electrical and flux equivalent circuit of the open circuit CT.

I will explain about the SMPS switching transformer working concept. I will also discuss the core type, losses, Litz winding type, voltage and flux generation sequence, and reason for the small size and less weight of the SMPS transformer and differences from the power transformer.
I will also tell about using 1952 numbers of transformers used in one of our projects.
