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

Can we inject more current in ct primary paralleling 2 loading transformers/Injection kit at a time?let ct ratio be (5000/1A)(per kit rating 2000A range),i need to inject 5000A,if this cant b done means wat is d optional?
Dear sir, I am working in wind mill division , pls explain Pls explain in details with formula My question is Wind speed 3.5 M/s Gen RPM is 1500 ( 25 K/w Production ) Wind speed 12 M/s Gen RPM is 1500 ( 220 K/w Production ) Why in 3.5 m/s generation was low , why in 12 m/s generation was high , Pls dont explain wind force or wind density , that one already i know For the above question RPM was same why the KW was different Answer : 1. Its depends on the density ( Force ) of the air Sir , Pls explain wit Formula sir
