Answer 1

Transformer is a magnetic device which couples two or more winding.Transformer AC operates AC excitation and change voltage level when side to other side.

N₁>N₂ Step down

N₁<N₂ Step up

$\frac{V1}{V2}=\frac{N1}{N2}=\frac{I2}{I1}$

Short circuit test:

$Z=\frac{Vsc}{Ioc}\Omega$

$X=(Z^2-R^2)^\frac{1}{2}$

$R=\frac{Psc}{Isc^2^{}}$

Open circuit test:$Zc=\frac{Poc}{Voc^2}$

$\frac{1}{Z}=Y=\frac{Ioc}{Voc}$

$bm=(Y^2-\sigma ^2)^\frac{1}{2}$
