If you want to measure ER of particular electrode ,you have
to disconnect it , to avoid the influence of other electrode
connected to the same equipment.If the cables are connected
in parallel ,the load sharing is inverse to the resistances
of cables so that the voltage drops in the cables are equal

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.
