For 35 HP motor how much amount of capacitor should be on in kvr to reduce the current bill1 380
Why transformer used in UPS??
The 3 phase Delta connection RB=440V, BY=350V,.......* is Line to Line voltage RY= ? And Formula....?288
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.317

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
