The material used in the manufacture of transformer cores must have a hysteresis loop with a very small area, as it is the area of the hysteresis loop that determines the hysteresis losses of the core material. The core material should also be resistive, in order to reduce eddy current losses (which is further improved by laminating the core). Many transformer manufacturers use their own variations on what is basically a silicon-steel.
A hysteresis curve, or loop, is a graph of flux density plotted against magnetising force, and basically describes the ease (or difficulty) with which the core material can be magnetised and demagnetised as the magnetising current changes magnitude and direction.

What is the use of core transformer?
500w iron core transformer .that kind of size
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
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.
What is the Al value of transformer?
AL means transformer core property
How do you reduce core losses in distribution transformer?
Reducing core losses is a design responsibility of the manufacturer. They do this by laminating the core (to reduce eddy-current losses) and carefully selecting the type of material used for the core (to reduce hysteresis losses). There's very little that you, as the user, can do about reducing core losses.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
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.
What is transformer tank?
The container the transformer core and windings are placed inside is the tank.
What is the purpose of transformer core?
yes core is usefull in transformer since it it increase the permeability for the flux (i..e,it offers less relucyance path thanj air ).Their by decresing the losses in the transformer.
What should be the construction core or shell typeof a step down transformer?
The core design has nothing to do with whether a transformer is used to step down, or step up, a voltage. Most transformers have core-type cores. Very large capacity (MV.A) transformers sometimes have shell-type cores, because they can be manufactured with less height. WebRep currentVote noRating noWeight
How to design Single phase domestic step up transformer and give its calculations?
THERE ARE THREE STEPS USED FOR FOR DESIGN THE SINGLE PHASE TRANSFORMER WHICH ARE UNDER:-1) CORE DESIGN.2) WINDING DESIGN.3) STAMPING DESIGN.1-CORE DESIGN:-THE FIRST STEP IS DESIGNING SUCH SMALL TRANSFORMERS IS TO SELECT TURNS PER VOLT DEPENDING UPON (VA) RATING OF THE TRANSFORMER.THE TABLE 1 GIVES THE VALUES OF TURNS PER VOLT(Te) FOR VARIOUS (VA) RATING.TABLE 1:-VA RATING TURNS /VOLT VA RATING TURNS/VOLT------------- ---------------- ------------- ----------------10 23.3 200 3.515 17.5 250 2.820 14.0 300 2.725 11.7 400 2.250 07.0 500 2.075 05.6 700 1.7100 04.5 1000 1.6----------------------------------------------------------------------------------------
