Recently we had experienced following problem
All RCCB breakers (connected to the load as well as spares)
connected to various UPS systems at various floors at a
high rise building tripped during a power break down and
upon starting up of generator.This Generator is recently
inducted into the installation. Can any one explain the
reason behind this tripping.
Regards

How relay works, reverse relay, master relay, os relay, earth fault relay and what is its setting point
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.
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
