if transformer core is made of copper instead of steel which losses will increase..please explain..

Answer / chandan kumar

hysterisis losses increases bcoz high grade steel is solenly
used in core material to reduce hysterisis losses while
laminated core is used to reduce eddy current losses.and
copper losses occur due to resistences of primary and
secondary windings....

Answer / somu0507

The main purpose of iron core is to provide low reluctance path.The copper has much lower permeability(approximately equal to 1) than iron and has comparatively higher conductivity. The following effects will occur if copper is used instead of Iron (for same supply of voltage and frequency):
1-It can be seen from voltage equation of the transformer that if supply voltage and frequency is constant then require flux is constant. to produce same flux, very high magnatising current will be required (as copper has very high reluctance than iron) which will result in VERY HIGH COPPER LOSSES in primary winding. Consequently the primary winding may get burn.
2- As the copper has higher conductivity HIGHER EDDY CURRENT LOSSES will occur.
2- Being a non magnetic material, Copper has very narrow Hysteresis loop, hence HYSTERESIS LOSSES WILL BE LESS.

Answer / anil kumar

the main purpose of core is to proviod low resis path .to that steel is used. if we use copper,hence large amont of eddy currets will produce causes short circuit.hence eddy loss plays main role.

Answer / saikrishna

if transformer core is made up of copper the conductivity of
copper will be more and hence eddy currents will flow
through core therefore eddy current losses will increases.
