How not to short-circuit the clean energy transition
The most typical type of fault is a short circuit. On the power grid, short circuits can occur, for example, when two wires touch, or when a tree touches a wire. This causes the generators to produce a big surge of electrical current. This is called fault current, and it can lead to fires and damage equipment if not corrected.

Why does a short circuit occur?
The ramifications of a short circuit can vary widely. It can result in a violent event if the amount of current available from the battery to flow through the short circuit is extremely high (as in the case of a car battery), or in a non-event for a low capacity battery, such as short circuiting a AAA alkaline battery. Hope this helps.
