Seperate Cavern/Hall for Gen. and Transf.-Why?
Seperate Cavern/Hall for Gen. and Transf.-Why?
(OP)
Hi all, there is always seperate cavern for Transformer and machine (generator) in under-ground Power House. Why? The reason I could think of:
i. It is typical in Power plant with bigger machine and more no. of units.
ii. Safety. ( I read in here somewhere that in-case of flooding etc, transformer is at risk of explosion if it is in same hall as generator and turbine units).
What are others?
My next question is while dimensioning Power House, in-order to calculate length of Power House, I have to also consider length of control bay of 20 m ( referred one hydropower handbook). Isn't it bit too much? What does other standard books and your experience say??
Your help/ insights will be really appreciated.

What about my second part of question? Someone can throw some light on it. :)

There are international standards on design of underground power houses( I know there is an Indian Standard)where you will get more details.

Control bay (aka erection bay / repair bay) has to be dimensioned to accomodate such assembly / disassembly works.

Edison, thanks. But in the handbook of hydroelectric engineering, they have given control bay and service/ erection bay seperately in the calculation. I assumed that by control bay they meant control room.Is it same??
