How Is A Transformer Wired?

Summary

As per a renowned power transformer company in Noida, the increasing demand for electricity is directly creating a market for effective changes in the supply of the electricity which keeps the profits uncompromised at various levels. Every single factor linked with transformers is considered in detail to reach a successful commercial plan. For instance, the power transformer manufacturers in India are working on new patterns of transformer configurations to satisfy the varied demand of power transformer prices in Delhi. Every transformer has a pattern of wiring which can be easily distinguished from a type of transformer to another. If you will see the wiring of high voltage power transformers, they will be quite different from that of the autotransformers. We considered some common patterns of transformer configurations which are marketed by the experienced power transformer manufacturing companies of the country.

It is no rocket science to merely know that the working of a transformer is rocket science (metaphorical only). Yes, the wiring of any transformer is a major component which decides the effective working of the transformer with proper utilisation of safety parameters. In this regard, the configuration of the transformer is quite important. Different types of transformer configurations are available. But certain factors have to be kept in mind for concluding on the type of any transformer configurations. The transformer configurations the conductivity pattern of the transformer, the levels of optimal voltage to be administered by the transformer, the size of the transformer, and the cost-effectiveness of the working of the transformer. Let's see the different patterns of transformer configurations in detail now.

1. Autotransformer

With creditable points of efficiency, autotransformer or referred to as Variac with their respective company names, autotransformers are provided with a continuous output voltage from zero. Unlike a conventional two winding transformer, in an autotransformer, both the primary and the secondary windings are magnetically connected to a laminated core of the transformer.

2. Center Tap

Commonly referred to as CT, Center Tap is used on an average basis. With the secondary side having three wires in the outward direction, the secondary coil is connected with the middle wire on the output side of the transformer. The grounding of center tap's outward wires can help in administering dual volt sources. In this case, such transformers are also connected with a converter which comprises of both a rectifier and a filter.

3. Dual Input

With the primary separated to provide four wires on the primary side, the dual input configuration of wires in a transformer is preferred in regions with both 120 V and 240 V of line voltage. To provide a clear understanding of the connections with respect to 120 line voltage and 240 line voltage, a help manual is provided along with it.

4. Dual Input and Output

A dual input and output configuration of wires in the transformer provide four wires and also four wires out of the transformer. This setup is recommended for its benefits of versatile performance.

5. Dual Output

As the name suggests, the dual output configuration of wires in the transformer includes the separation of two connecting wires which are then put outside. If the current in this configuration is reversed, the system will give 0 volts. For dual output configuration of wires in the transformer, hot wire foam cutters are a common choice because the latter provides a flexible range of both the diameters and the lengths of the wires in the connection.

6. Single-phase Power

In single-phase systems, only a single winding induces flux in the laminated core of the transformer. The compact size of the single-phase transformer which is preferred for indoor set-ups and heating needs compliments the versatility of these transformers which can be enhanced by keeping up the same size of both the primary and the secondary windings. 6

7. Three-phase Power

The bulky size of transformers with three-phase power is because of their composition of three circuit conductors. Even three single-phase power systems can be used to make one three-phase power system in a transformer. The three-phase transformers have three primary windings and three secondary windings. Also, the windings of the same three-phase transformer can be configured in its own way.
