What should I do if the transformer suddenly short-circuits? Do you know these reasons?
To deal with transformer short-circuit accidents in daily operations, it is necessary to find out the essence of the problem through inspection and testing. When the transformer suffers from a sudden short circuit, both the high and low voltage sides will be subject to a large short-circuit current. In the short time before the circuit breaker can be disconnected, the short-circuit current will generate an electromotive force proportional to the square of the current that will act on the winding of the transformer. Electrodynamic force can be divided into radial force and axial force.
