Transformer
is Static Device that transfers electrical energy from one electrical circuit to another electrical circuit. Transformer works on Principle of Mutual induction
Stage down and stages up the voltage and also the level of current with less or
less. Transformer is an AC device without frequency
The
level step of the voltage is changed by sub-station or downstream transformer
was invented by Michael Faraday or Joseph Henry in 1831, which is called
transformer
Working Principle of transformer -;
Uses Faraday’s electromagnetic induction Rule to work for An electrical transformer – “Rate of
change of flux linkage with respect to time is directly proportional to the
induced EMF in a conductor or coil”.

What is Transformer |
The important Material of an electrical transformer are primary
winding, and secondary winding and magnetic core, . The primary winding is connected to an electrical supply , from where magnetic flux is initially
produced. These coils are insulated from each other and the main flux is
induced in the primary winding from where it is passed to the magnetic core and
linked to and through the low reluctance path of transformer’s secondary winding
The core relays the flux to the secondary
winding to create a magnetic circuit that closes the flux, and a low reluctance
path is placed within the core to maximize flux linkage. The secondary winding
helps complete the movement of the flux that begins at the primary side,
and using the core reaches the secondary winding. The secondary winding is able
to pick momentum because both winding are wound on the same core and hence
their magnetic fields help to create motion. In all the types of transformers,
the magnetic core is assembled by stacking laminated steel sheets leaving the
minimum required air-gap between them to ensure the continuity of the magnetic
path.
Construction of Transformer -:
Electrical
transformers are machines that transfer power from one electrical circuit to another electrical circuit with changing voltage level but no frequency change. present time, they are designed
to use AC supply, that means that fluctuation in supply voltage is impacted by
the fluctuation in the current. So, an increase in current will bring about an
increase in the voltage and vice versa.
Transformer
is two winding (primary and secondary) and a laminated iron core is the
function of the iron core in the transformer, the principle is to provide the
path of low reluctance to the magnetic flux
If
we have an ac supply, we can lend the iron core to reduce the losses, then the
silicon steel material is used for laminate. The quantity of side silicon steel
is high
