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.

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….

Dear sir, we are getting voltage fluctuations suddenly for 2 or 3 minutes again it becomes normal. we checked each and every connection some times we are getting 110 volts like that from earth to neutral again it is reducing we are getting supply from 45 kva DG set give earthing properly.
