These are transformers specially designed to reduce the losses.

to reduce the iron losses i.e hysteresis and eddy current
losses,they use high graded silicon core and perfect
lamination's with good insulation.

but the copper losses depends upon loading the transformer.

why aggregate is placed all around substation ground.
