There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical. The electromagnetic voltage transformer is a wire-wound transformer. The capacitor voltage transformer uses a capacitance potential divider and is used at higher voltages due to a lower cost than an electromagnetic VT.There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical.

Three-phase transformers are a type of transformers that are used to change voltages of electrical systems with three phases. There are different types of configurations, namely: star-star, delta-delta, star-delta, and delta-star.
What are the main types of transformer?
The different types of transformer are Step up and Step down Transformer, Power Transformer, Distribution Transformer, Instrument transformer comprising current and Potential Transformer, Single phase and Three phase transformer, Auto transformer, etc.
There are several transformer types used in the electrical power system for different purposes, like in power generation, distribution and transmission, and utilization of electrical power. The transformers are classified based on voltage levels, Core medium used, winding arrangements, use and installation place, etc.
What is the main function of transformer?
The function of the transformer, as the name implies, is to transform alternating current energy from one voltage to another voltage.
A three-phase transformer is made of three sets of primary and secondary windings, each set wound around one leg of an iron core assembly. Essentially it looks like three single-phase transformers sharing a joined core as in Figure below. Three phase transformer core has three sets of windings.
Therefore, RMS value of emf per turn = 1.11 x 4f Φm = 4.44f Φm. This is called the emf equation of transformer, which shows, emf / number of turns is same for both primary and secondary winding. For an ideal transformer on no load, E1 = V1 and E2 = V2 .
What is the main purpose of transformer?
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to step up or step down voltages and works on the magnetic induction principle.
A transformer is an electrical device designed and manufactured to step voltage up or step down. Electrical transformers operate on the principle of magnetic induction and have no moving parts.
Transformers can be used either to increase the voltage also known as stepping up the voltage, or they can decrease the voltage also known as stepping down the voltage. Less energy is lost if the voltage is very high. Usually, electrical utilities use high voltage in long-distance transmission wires.

How do you make a 3 phase neutral?
The only way to get a neutral point in a three-phase system is to use a star topology. The only (real) way to convert a delta into a star topology is to use a delta-to-star transformer (AKA Delta-Wye transformer).
What is emf per turn?
Induced emf per turn = rate of change of flux per turn. Therefore, average emf per turn = 4f Φm .(Volts). Now, we know, Form factor = RMS value / average value. Therefore, RMS value of emf per turn = Form factor X average emf per turn.
The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force (EMF).
