If blowing of HT side fuses result in zero magnetising
current in the primary winding, then there will not be any
voltage in ry,rb,yb on the secondary side

Answer / t. eswara rao

If the primary is DELTA connected, there is no voltage in
the secondary for this case. if primary is star connected
and star point is earthed then it depends upon the
configuration of the transformer, whether it is star-delta
or star-star.It also depends upon the star point earthing
whether it is solidly earthed or through NGR.

Answer / harish

depends upon the configuration of the
transformer...whether it is star delta,star star.....

Answer / shashidara

usually distribution trans. are of del/star type . there will b no vltg at secndry

Answer / hb umesh shetty

there is no voltage in the secondery side,

how to find 5 kilo meter long under ground 33 kv cable fault location if IR VALUE shows 0.05 M ohm @5000 volt.and cable fault locator shows some time fault distance 3 kilo meter ,3.7 kilo meter and some time 1 kilo meter? now how to find the fault location that where is leakage. note--it is tested with 5000 kv megger and insulation resistance is 0.05 M ohm. and some time 0.03 M ohm comes.

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.
