To optimize the use of copper in the transformer/reactor coil, the coils are wound in a circular pattern. This necessaites the core section also to be circular. Normally, core is built out of steel laminations(CRGO) to reduce the eddy current losses. The core could be toroidal or stepped in section. While toroidal cores can be built in circular section, stepped cores have to be built such that the section is closest to a circle. This is why the cores are stepped in formation.
What else can I help you with?
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
Explain why cruciform shape is used in transformer core?
to reduce core reluctance..
What is transformer tank?
The container the transformer core and windings are placed inside is the tank.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
What type of current must be used with a transformer?
DC current cannot be used in a transformer only AC will work. A transformer needs the continual build and collapse of the magnetic field to keep the iron core from reaching saturation. Only alternating current will transfer power through a transformer.

What is the significance of stepped core?
A transformer's windings are pre-wound around insulated 'formers' or tubes of circular cross section. To achieve maximum flux density, the core should ideally be of circular cross-section, too. A 'stepped core', then, describes the way in which the widths of the outer laminations of a transformer's core are progressively reduced ('stepped') in order to achieve a roughly-circular cross-section.

Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
How dc supply is given to transformer used in push pull amplifiers?
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.
What is the use of core transformer?
500w iron core transformer .that kind of size
What is core type and sell type transformer?
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
CAN you able to use any other thing instead of iron core in transformer?
shell type core can be used
What happens to the current if the potential difference is stepped-up in an ideal transformer?
In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.
What Is a core-core type transformer?
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
