What else can I help you with?
Why primary side of transformer blown?
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.
Why are short time rating of transformer is high?
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.
What happens to a wire if the current capacity is 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.
How long can the maximum ampere rating on a generator be exceeded?
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.
Why is it not good to operate a transformer above its nominal voltage?
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...
Under which circumstance may the Maximum Person Capacity of a vessel be exceeded?
The maximum person capacity can be exceeded if the vessel is 26ft or longer.
Why does the white tailed deer population drop when the carrying capacity is exceeded?
the environment cannot sustain the number of organisms and food becomes too scarce for such a population to survive
What is the worlds carrying capacity?
The world's carrying capacity is the maximum population size that can be sustained by available resources and without causing detrimental effects on the environment. It is a complex and dynamic concept influenced by factors such as technology, lifestyle choices, and resource management. Estimates of the Earth's carrying capacity vary widely, but many experts agree that it is currently being exceeded.

The deffinichion for carring capacity?
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!
Why are short time rating of transformer is high?
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.
Meaning of consumer satisfaction?
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.
What happens if the carrying capacity is exceeded?
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".
Define stress tolerance capacity?
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
Which is a valid statement about the soviet union from the time of the bolshevik revolution through 1991?
demand for consumer goods exceeded production
What percentage of the trailer's recommended load capacity should not be exceeded by the combined weight of the vessel and its engine?
D 90%
What happens to a wire if the current capacity is 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.
