Transformer Help: Immediate Effect of Short Primary Winding

[glasgowkizz]

If the primary winding of a transformer is shorted, what will be its immediate effect to the transformer?

 

[vk6kro]

It depends whether the transformer is connected to a power source or not.

If it isn't there will be no effect at all.

If it is, then the power source will be shorted out as well and this would cause circuit breakers or fuses to cut the power.

If it was a complete short circuit, from end to end of the primary, the transformer would be unaffected, although it would have to be repaired before it could be used.

If it was a partial short circuit, the remainder of the winding that wasn't shorted could be destroyed.

A short of just a few turns can cause overheating of the transformer.

Thanks a lot for answering!

The immediate effect of a shorted primary winding in a transformer will depend on the type and design of the transformer. In general, a shorted primary winding can cause an increase in the primary current, leading to overheating and potential damage to the transformer. This can also result in a decrease in the output voltage and efficiency of the transformer. It is important to address a shorted primary winding as soon as possible to prevent further damage to the transformer and ensure its proper functioning. A qualified technician should be consulted to properly diagnose and repair the issue.
