A beach day, a memory of sea waves, and a question that finally gets answered: why do we call RMS the “effective” or “heating” current of AC? A clear, step-by-step explanation for beginners.
Before you calculate short-circuit current, IEC 60909 makes you learn the terms first. Here’s every term explained in plain English — no jargon, no confusion.
While current determines the size of the copper or aluminum bar, the bus voltage is the primary factor in determining the follwing parameters:
After exploring about nominal voltage, I came to the next parameter of power system electrical equipment which is “rated voltage”. And I also understand that the manufacturer considers this voltage as the best voltage to design their electrical equipment. Hence, I’m explaining about the rated voltage in this post. What is the meaning of the … Read more
