it is a static device,is enery trasfer for one end to
anther end without chaning frequency

Answer / syed

A transformer is a device that transfers electrical energy
from one circuit to another through inductively coupled
conductors—the transformer's coils. A varying current in the
first or primary winding creates a varying magnetic flux in
the transformer's core, and thus a varying magnetic field
through the secondary winding. This varying magnetic field
induces a varying electromotive force (EMF) or "voltage" in
the secondary winding. This effect is called mutual induction.

Answer / gobi

Is is a device which is not only used to transfer the electrical energy but also used to manage the loss by varying the voltage level..........

Answer / sajid

transformer is a static device which is sed to transfer
energy from one side to (primary to secondary) without
change in frequency. transformer is of two types step up n
step down.
step up transformer is used to increase low voltage to high
voltage n step down transformer decrease from high voltage
to low

Answer / bhuvan sharma

A transformer is a Ac static device this known as static because there is no moving parts only energy(Voltage) means is transformed by the electromagnetic induction from primary winding to the secondary winding.
a)Distributed Transformers-which is used to step down the voltage.

b)Power Transformers - Which is used to step up the voltage.

I did oil BDV test of 1600 KVA trafo 20KV/400V as per IEC 156. Result is 1) 58 KV 2) 58 KV 3)40 KV 4) 50 KV 5) 58 KV 6) 18 KV. Avr is 47 KV. Can we say oil is still ok even in the 6th test BDV is 18 KV ?
