Under normal operation, the load impedance is very high, essentially resulting in an open circuit; as a result, only a very small load current flows on the secondary side. When the secondary side is short-circuited, the load impedance becomes zero, which causes a large short-circuit current to flow. This can damage the voltage transformer, so it is essential to prevent short-circuits on the secondary side during its operation
