Question

What is a short circuit fault?

Answer

A short-circuit fault in a power system is an abnormal condition that involves one or more phases unintentionally coming in contact with ground or each other. Thus, short-circuit protection is necessary to protect personnel and apparatus from the destructive effects of the resulting excessive current flow, which is caused by the relatively low impedance of the short-circuit fault connection.
