The consequences of a short circuit

The consequences of a short circuit are very serious, so we need to do our best to eliminate all short circuit factors and calculate the short circuit current in order to correctly select the electrical equipment. To ensure that it will not be damaged by strong short circuit current. So that we can choose switching devices that cut off the short-circuit current, set electromechanical short-circuit protection working devices, select environmental protection devices and choose an original that limits the short circuit current, we need to calculate the short circuit current.
