How to perform short-circuit calculations. | EC&M

Performingshort-circuit calculationsrequires an understanding of various system components and their interaction.It's very important to understand the meaning of the term "short-circuit fault." Basically, ashort-circuit faultin apower systemis an abnormal condition that involves one or more phases unintentionally coming in contact with ground or each other.
