Working Principle Of Single Phase Transformer: How Does it Work?
Here is how the working principle of a single-phase transformerworks. It is entirely dependent on the common tendency of the electrical conductor to resist a change in the electric current flowing through it and of the coils on the same magnetic core.
Working Principle Of Single Phase Transformer
The alternating magnetic flux (Φm) sets in the core and links of the secondary winding when you apply a primary winding with an alternating voltage (V1). The magnetic flux links of both the windings are set up through the magnetic conduction in the transformer. Focusing on Lenz’ law,SecondaryEMF,E2=−N2dϕmdtTherefore,E2E1=N2N1From the equations stated above, we can clearly say that the generated EMFs in the primary and secondary windings depend entirely on the number of winding turns. If ?1 > ?2, then ?1 > ?2The primary EMF remains greater than the secondary EMF; thus, the transformer is called the step-down transformer.If ?2 > ?1, then ?2 > ?1This makes the primary EMF lesser than the secondary EMF; this time, the transformer is called a step-up transformer.If you connect a load across the second winding terminal, then the secondary EMF will cause a current I2 that flows via the load. This is how a transformer transfers AC power from one circuit to another. You can see this action happening with a change in voltage level with no electrical connection between both circuits. The power is transferred magnetically from the input circuit to the output circuit. There is no change in the frequency while the electrical power transfer takes place.
What Are Some Types of Single-Phase Transformers?
These transformers are made to receive and output single-phase AC power.
Constant-Voltage Transformer (CVT)
Constant-Current Transformer (CCT)
Generator Step-up Transformer
Harmonic Mitigating Transformer
Industrial Control Transformer
Leakage Transformer (Stray-Field Transformer)
Neutral Grounding Transformer
Solar Power Transformer
Where is all a Single-Phase Transformer Used?
It is used for various small to mid-level applications in residential areas and commercial areas such as:
To lessen the long-distance signals that work in residential and light-commercial electronic devices.
For voltage regulation in television.
For home, inverters step down.
For power distribution in non-urban areas.
To isolate two circuits electrically.
