Transformer Windings
There are two types of windings usually used in a transformer. The winding receiving electrical energy is known as primary winding, whereas…
Transformer Tank
The factors such as weight, stray load losses and minimum cost are kept in mind while selecting the material for transformer tank.…
Voltage Regulation Of Transformer
With constant voltage applied in primary, the secondary terminal voltage will decrease due to voltage drop across its internal resistance and leakage…
Types Of Transformers
A transformer may be step up or step down. If the output voltage is greater than the input voltage, the transformer is…
Working Of Transformer
Nowadays, electrical power is generated for industrial and utility purposes by thermal power stations and large hydroelectric plants in the three-phase form…
Cooling Of Transformer
Transformer is a static device that converts one voltage level to another voltage level. Due to occurrence of iron and copper losses,…
Emf Equation Of A Transformer
Figure 1.22 shows the representation of alternating flux, varying sinusoidally, which increases from its zero value to maximum value (Φm) in one-quarter…
Transformer With Resistance And Leakage Reactance
Figure 1.32 shows the equivalent circuit of a single-phase transformer having load impedance ZL. Figure 1.33 is the equivalent circuit of Figure 1.32.…
