what is the ciruit diagram of transformer vector grup test?..

hi friend it depends upon the transformer group,whether
Dyn11,Dd0etc...and then we arethe condition makers and
proove by measuring voltage of different series......

what is the ciruit diagram of transformer vector grup test?..

Answer / thiyagarajan

it will depends upon the transformer vector group for eg
your having ydo means the primary power is in phase with
the secondary if yd11 means secondary is leading primary by
an angle of 30degree yo can draw vector diagrams as per
their phase angle then making short to any of the same
phases in primary and secondary by deriving you can apply
voltage across primary and measrure voltages as you will
get some conditions based on vectors

Answer / kishor

circuit diagram of transformer for vector group is nothing
but various phase angle betwen primary and secondary
voltages.we have to preadujested various vector groups
reading for reference.hence while checking a particular
group ckt. will sense reading with respt to refernce
value.final result will shows on screen with vector
drg.respt to preadugsted value and circuit.

Answer / vels

no circuit dioagram is needed
we apply voltage on HV side
measure voltage with respect to the condition of vector group and confirm the vector group
