Basic motor transformer generator79
Why transformer used in UPS??
The 3 phase Delta connection RB=440V, BY=350V,.......* is Line to Line voltage RY= ? And Formula....?114
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.118
