Answer / kunal

It is a large encased group of metal plates about the size
of a small house with 2 sets of insulated copper wires
wrapped around the plates -an input and output - to convert
a very high supply line voltage - maybe 44 thousand volts
to a lower voltage of 2200 volts that runs down the power
line poles in your neighborhood. Look at your street's
power poles and you will see a mini substation that
converts he 2200 volt to 220 volts and may supply several
homes.

Actually a substation transformer for a distribution
substation will reduce the incoming voltage from 115,000
volts or 69,000 volts to a lower voltage closer to 7200
volts that runs down the power poles in your neighborhood.
At your house there will be a small transformer that
reduces the voltage from 7200 volts to 240 volts to meet
the needs in your home.
