Why is silicon steel used in transformer core?
The core of the transformer made of silicon steel is because silicon steel itself is a magnetic substance with strong magnetic permeability. In the energized coil, it can generate a large magnetic induction intensity, which can reduce the size of the transformer.
How can hysteresis loss be reduced in transformer?
How do we Reduce Hysteresis Losses? Hysteresis losses can be reduced by using material that has less area of the hysteresis loop. Hence, high grade or silica steel can be used for designing the core within a transformer because it has extremely less area of the hysteresis loop.
Why silicon is added in core?
A Core Materials. The use of silicon iron as a magnetic core material was introduced in the early 1900s. Silicon iron has a relatively high permeability, and the increased resistivity due to the silicon helped reduce the eddy losses.
Why silicon steels are used for electrical transformer cores and cores of other electrical devices Mcq?
In the electrical transformer core, mainly two types of losses take place which are termed as iron or core losses. The addition of silicon in the earlier soft magnetic material iron, increases the resistivity, decreases the hysteresis loss, increases permeability and virtually eliminates aging.
Why silicon steel is used in electrical machines?
As Si is semi-conductor and Fe is a conductor so resistivity ρFe>ρsi. As resistivity increases the eddy current loss decreases. Hence silicon steel is used in electrical machines.
Why silicon steel is used in DC motor?
Why is silicon used in transformers?
Silicon steel is a soft magnetic material that is used in electrical power transformers, motors and generators. It has a high silicon content of about 3.2 mass \%, which increases the electrical resistivity of iron and, therefore, reduces eddy current losses.
What is the composition of the steel and silicon steel in transformer core?
C) Steel 93\% and Silicon 7\%.
What is the reason why silicon steel is used in electrical machines?
