Problems with high-level voltages will be cumbersome to bear. However, dealing with higher voltage levels is not that risky now with advanced technological solutions. Yes, today’s spectacular high voltage transformers are the best solutions to handle high voltages for several industrial applications.
Electrical and electronic applications need sufficient voltage levels – low or high. High-voltage transformers are the most special among the transformer varieties as they accommodate efficient power-based operations in single-phase and three-phase power means.
What are High Voltage Transformers?
The transformers that deal with high voltage levels between 33kV to 220kV is called as high-voltage transformers.
As you know, the transformers increase or decrease the voltage levels as per the requirements. These high voltage transformers are also available in step-up and step-down models.
That means, they can supply higher voltage output at the secondary end of the transformer or decrease the high-level voltage to lower voltage levels for customized applications.
How do they work?
The transformer works on the principle of Faraday’s mutual electromagnetic induction. It has primary and secondary coils wound on an iron core. The power flows through the primary coils and creates a magnetic field that transfers through the core to the secondary coils. At the secondary end, the induced magnetic field enables the transfer of the power to the load or equipment.
The high voltage transformers also work in the same way. The step-up high voltage transformers have a lesser number of coils in the primary end than that in the secondary end. The power voltage increases to the adequate high voltages required for the efficient performance of the load.
In step-down high-voltage transformers, the primary side deals with higher levels of voltage. It has the number of coils than that at the secondary end. So, the voltage level is decreased at the secondary end.
Apart from the step-up and step-down models, they are even designed in such a way that the primary and secondary ends have the same number of coils. Then, the voltage levels neither increase nor decrease. So, the voltage remains the same.
But, such high voltage transformers separate the load from unexpected voltage variations and protect the equipment from unnecessary damage. They are efficient isolation and ultra-isolation transformers used for the absolute safety of several types of sensitive electric and electronic equipment.
Whatever is the model, they have to be able to deal with high voltages. Therefore, their design, structure, and strength should be excellent and standard for long-lasting use.

Stringent Designing Considerations of High Voltage Transformers
During several industrial operations, these transformers may face transient voltages and surges. Under such conditions, the insulation of the transformer may be damaged. So, it is necessary to design the high voltage transformers with the greatest insulation characteristics.
Also, the cooling means to dissipate the heat produced should be efficient. Generally, oil-based cooling is used in high voltage transformers.
As they deal with high voltages, the surrounding core should also be standard enough to avoid unnecessary losses. Therefore, world-class raw materials are to be used to design the windings, core, and other significant components of the transformers.
Moreover, high voltage transformers with greater efficiencies enable no losses. The voltage rating at the input and the output will be the same for such transformers. So, when designing them, it is necessary to consider the load capacity and design the capacity of the transformer with an associated rating.
When purchasing a high voltage transformer, it is important to keep in mind certain parameters like –
o Maximum Secondary Voltage Rating
o Maximum Secondary Current Rating
o Maximum Power Rating
o Output Type
Where are they used?
High voltage transformers are used for several industrial applications. They play a great role in power transmission. At the transmission lines, the power with high voltage is transferred to avoid losses. Therefore, the step-up high voltage transformers are used to increase the voltage and transmit the power efficiently. These are the major users in sub-stations and generating stations etc.
