What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.
It is either a short in (1 or more) of the windings (if its multi-phase) or the applied voltage was too high. What is the application, size (wattage), voltage, a number of phases for this Xfmr? I might be able to help you troubleshoot it further with this information.AnswerIt depends on what you mean by 'blown'! Do you mean the primary fuse has operated? If so, then it's likely the transformer's load has exceeded the capacity of the transformer.
Because a transformer is a big lump of metal that takes time heat up, so if the load is on and off in a short time, the load rating can be exceeded.
The wire overheats. In a bad case, a fire can be started. Note that, sometimes, current capacity is actually more a factor of insulation capacity rather than wire size.
Sometimes only seconds, it depends on the way the manufacturer rated the "maximum" capacity. In general, electrical equipment should be operated at no more than 1/2 of a maximum capacity.
Overexcited Transformer.Operation above the rated supply voltage causes the ferromagnetic core to enter saturation; this means that the primary inductance is reduced and since the primary current is limited by primary resistance +inductance then the primary current will increase and possibly cause the primary winding current capacity to be exceeded. Also the iron core hysteresis loss will likely increase and cause the core temperature to rise. We have not considered eddy currents in the core, probably these are less than the hysteresis core loss.Addition:also the stresses that caused by increasing the voltage will over heat the transformer by mean the life time is redused, for example: if the life time for a transformer is 20 years this number will decrease due to operating the transformer on a higher voltages than the rated...
the environment cannot sustain the number of organisms and food becomes too scarce for such a population to survive
The maximum person capacity can be exceeded if the vessel is 26ft or longer.

The "definition" of "carrying" capacity in the animal world is: "The maxium population of a given species that an ecosystem can support without being degraded or destroyed in the long run. The carrying capacity may be exceeded, but not without lessening the system`s ability to support life in the long term." This answer was taken out of a college text book on Environmental Science By: Richard T. Wright I hope this helps explain your question. Good Luck!

Consumer Satisfaction can be defined as a degree of person's satisfaction about a product, which fulfilled his expected requirements and exceeded his expectations regarding the product's performance.
if can't sleep with 20 minutes means you have exceeded the limit of stress if you can't forget something after 3 days means you have exceeded the limit of stress
It will likely descend into warfare as happened on Easter Island, and savagery will continue until the population drops below whatever remains of the carrying capacity. However, the warfare may also diminish both the human resources and Natural Resources and infrastructure to the point that no meaningful recovery is possible. Think TSE's "not with a bang, but a whimper".
demand for consumer goods exceeded production

Oh, sure. People overload boats beyond their "maximum" capacity all the time, and sometimes it doesn't kill them. But a lot of the time, it DOES kill them, which is why there's a published "maximum capacity" for every boat.
