Question

If a high voltage is required we use step up transformer where as if a high current is required a step down transformer is used. explain it please

Answer 1

Need for step up voltage 

   The generating voltage in India is about 11 kv. This voltage has to be supplied to the consumers at various places from the generation point. If the generated voltage is transmitted as such then there will be more losses in the transmission line as a result there won't be any voltage available at the receiving end (consumer side). Hence in order to transfer the power efficiently with minimal losses the step up transformer is used where voltage is stepped up from 11 kv to 230 kv and then transmitted.

Need for step down voltage

   The voltage requirements at the distribution side varies accordingly depending upon the consumers at various levels. The voltage requirement at industries differ from that of household appliances. Industries will have high voltage requirements of about 11 kv and thehousehold appliances will have voltage requirements of about 230 v.
   Hence now in order to distribute the consumers required voltage levels the step down transformers are used where the voltage is stepped down from 230 kv to 11 kv or 230v.
