Mell What makes a transformer so efficient?
Transformers use a solid conducting core, hence there is very less leakage of flux as the core offers lesser reluctance (reluctance = resistance for flux) than air. Due to these reasons a transformer has very high efficiency.
Which transformer has the highest efficiency because?
What is the basic principle of working of a transformer ?
Why transformer has high efficiency motor or generator?
The transformer is more efficient because , there is no moving device to lose energy mechanically as in case of DC motorsand generators , there is no air gap between two coils transferring energy in a transformation and there is no loss of energy in making AC to DC and DC to AC by using convertor or commutators and …
Why is a transformer more efficient than other machines?
Answer Wiki. Transformer is one of the most efficient device in electrical. The efficiency of transformer is greater than any other electrical machines. This is due to transformer is a static device and there are no mechanical losses in transformers.
How is copper loss related to the efficiency of a transformer?
It is clear that Cu loss is proportional to square of the current, and current depends on the load. Hence copper loss in transformer varies with the load. Just like any other electrical machine, efficiency of a transformer can be defined as the output power divided by the input power. That is efficiency = output / input .
Are there mechanical losses in an electrical transformer?
An electrical transformer is an static device, hence mechanical losses (like windage or friction losses) are absent in it. A transformer only consists of electrical losses (iron losses and copper losses).
Which is the most efficient device in electrical?
Transformer is one of the most efficient device in electrical. The efficiency of transformer is greater than any other electrical machines. This is due to transformer is a static device and there are no mechanical losses in transformers. While if you say DC machine then there is a rotational part so their losses is greater than the transformer.
