Answer / r.nandha kumar

yes,it is possible by measuring the winding resistance of
primary & secondary.High voltage side will have high
resistance value than th low voltage side

Answer / rahul bawangade

as per working principle transformer , there is no primary &
secondary of transformer . transformer can be work in either
ways.

but if we have to check HV & LV we can do with multimeter .
as per transformer ratio

V1/V2=N1/N2=I2/I1. ................eqn 1
&
R =rho L/A . ...............eqn 2
\
as LV side requirement of current more & no of turns are
less , & cross sectional area of conductor is lare as per
eqn no.1& 2,resistance offered by conductor is less as
compare to HV .

Answer / desingurajan

initially transformer have no primary or secondary. wherever we giving input, that is called primary. and another end is called as secondary......

Answer / rsbangra

As looking the tranformer one side primary and other side
secondary as per name plate, we can mesure resistenance by
just r=v/i v=rating voltage and i= rating current ,voltage
take root 3 of line voltage, so we recive resistanse value
ht or lt side, as other view insulatior are used ht side so
high and lt side lower leanth and small size.

What is Partial Discharge test .Please specify that this test can be test on 11/0.433 KV,630 KVA Transformer.
