| in single phase we get 220 volt and in three phase 4420 v
why this
second Ques= in case three phase star conection our
neutrul becom disconect what happan
3 Q=== a three phase house load and have unbalce load on
different pahse diffrent current eg phase a 7A b 8A c
5A and voltage is 440 than how calculate it total load in
kw pl give formula thanks | | 7 |
| why we step down voltage level from 33kv to 11kv and 11kv
to 415v.Instead we can step down voltage from 33kv to 415v
directly using single transformer. | | 4 |
