It is type of transformer which is used
to step up the voltage from low to high value in order to make it
applicable for high rated appliances. Not only for high rated appliances
but also for transmission in power distribution systems. It is critical
in this role. Power distribution systems depend heavily on step-up
transformers to generate the high voltages needed for more efficient
long-distance power distribution. (And yes, there are step-down
transformers at the other end to make the voltages more "user friendly"
and less dangerous.)
Working :
A step up transformer takes a specific input voltage on the primary coil
and induces a specific higher voltage on the secondary coil, hence the
name step-up. The secondary voltage is determined by the ratio of turns
on the secondary to primary coils respectively.
For example, a transformer with 100 turns on the primary and 1000 turns on the secondary will produce a secondary voltage that is 10 times the primary voltage.

For a more in depth explanation of how transformers actually induce voltage on the secondary coil, You will most likely see a 'step-up' transformer on neon signs. The
next time you're at a restaurant or bar, look at their neon sign. You'll
see a black box (4" x 4" x 6"w) connected to the sign (usually). This
is the transformer, and it takes 120 volts AC and steps it up to 7500 to
10,000 volts AC. This excites the neon gas and causes it to glow.
A step-up transformer transforms voltage to a higher level. Like 120 volts to 277 volts.
