2. What isTransformer? ID 143-33-2145
Transformer is a static device which transformers A.C electrical power from one voltage to
another voltage keeping the frequency same by electromagnetic induction
Part Of Transformer:
1.Main Tank
2.Radiators
3.Conservator
4.Explosion Vent
5.Lifting Lugs
6.Air Release Plug
7.Oil Level Indicator
8.Wheels
9.HV/LV Bushings
10.Filter Valves
11.Oil Filling Plug
12.Drain Plug
13.Cable Box
Filling Pipe
Visual oil level eye indicator
Lifting Lugs
HV Bushing
LV Bushing
Tap Changer
Pulling Lugs
CorrugatedTank

3. the basic structure of a transformer ID 143-33-2079
Primary coil-Connected to electrical supply
Secondary coil-Connected to electrical load
Working Principle :
When the switch is closed:
1.Current in primary coil increases
2.Creates increasing magnetic field in
primary coil
3.Induces voltage in secondary coil
4.Lamp lights up

4. Classification of transformer 143-33-2091
As per phase As per core As per cooling system
1.Single phase 1.Core type 1.Self -cooled
2.Three phase 2. Shell type 2.Air cooled
3.Oil cooled
