High Voltage Transformers convert voltages from one level or phase configuration to another, often from higher to lower. They may have electrical isolation, power distribution, and control and instrumentation functions. To convert voltage and current levels, this transformer design uses the concept of magnetic induction between coils. In a nutshell, a high voltage transformer is a transformer that functions at a high voltage level. High voltage transformers are often utilized for testing in high voltage laboratories. When the insulation under test fails, these high voltage transformers are exposed to transient voltages and surges during regular operation.
Transformers are classified based on their function, usage, construction, and so forth. It should note that these categories may occasionally overlap - for example. A transformer can be both a three-phase transformer and a step-up transformer simultaneously. Some of the top electrical engineering publications discuss the workings of a transformer in more depth.
The following are the many kinds of transformers:
Step Up and Step Down Transformers
Step-up transformers convert low voltage (LV) and high current values from the transformer's primary side to high voltage (HV), and recent standard deals on the secondary side.
Three-phase and single-phase transformers
Because three-phase transformers are less expensive than single-phase transformers, they are commonly used in three-phase power systems. However, when space is limited, it is preferred to utilize a bank of three single-phase transformers rather than a single three-phase transformer unit since it is simpler to move than a single three-phase transformer unit.
Autotransformer and two winding transformer
When the ratio of the high and low voltage sides is higher than 2, a two-winding transformer is commonly utilized.
Transformers, both outdoor and indoor
Outdoor transformers, as the name implies, are intended for installation outside.
Transformers of the Oil Cooled and Dry Type
This categorization is for the transformer cooling system employed inside the transformer.
Transformer with a core
Transformer windings are classified into two types: core type and shell type. Some transformers look like berries.

What exactly is a high-voltage transformer?
A high voltage transformer is a transformer that works at a high voltage. High voltage transformers are often utilized for testing in high voltage laboratories.
What is the operation of a high voltage transformer?
To avoid wasting energy, the transformer core directs the passage of the magnetic field between the primary and secondary coils. When the magnetic field reaches the secondary coil, it causes the electrons inside it to migrate, generating an electric current by electromotive force (EMF).
What are the three kinds of transformers?
For example, some transformers are designed to convert between main and secondary voltage levels. The three kinds of transformers are depending on voltage. Step-up and Step-down Isolation Transformers
What is the difference between LV and HV in a transformer?
LV is an abbreviation meaning "low voltage." HV is an abbreviation meaning "high voltage." SquareD/Schneider Electric does not label low voltage dry-type distribution. Transformers are classified as "main" and "secondary." The primary side of the transformer is linked to the source, while the secondary side is connected to the load.
Why do transformers need such a high voltage?
High voltage transformers convert voltages from one level or phase configuration to another, often from higher to lower. They may have electrical isolation, power distribution, and control and instrumentation functions.
