in our sub station why we step down firstly 33kv\11kv then
11kv to 430v. can we direct step down 33v to 430.v.
Answer Posted / ramesh
Generally we can step up high voltage to low
or low voltage to high voltage for a possible range.
which is balance for our economical stage
but technically it is possible the turn ratio of the
transformer would be large and it will increase the size as
well also differs cost of the transformer.
so that generation for 11 kv increases up-to level ll 750kv
11kv-33kv-66kv--132kv---400kv--750kv
step down as 11kv-440V- 230V-110V

Sir,In our company there are 3 caterpillar make(capacity:(1) 3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make (capacity:11KV,3.8MW)gas engines utilised,all are running in paralell. There are three transformer utilised,(1) 6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence voltage:7.2% used for one generator of 2.5MW & (3) 5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one generator of 2.5MW.all generator breakers capacity of 1250Amps. Sir,I want the details of fault level calculation of generator,transformer individually & for whole system. If you require any information from me.feel free for contact me sir.pl.send the answer of my question as the earliest as possible.
