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 / puneet kulshreshtha
IN PAST MANY OF TIMES WE USE 33/.430 KV S/S
BUT IT IS VERY EXPENSIVE SO WE USE 11/.430 S/S FOR EASY

why we use sinosidal voltage / current instead of others in system?
if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
