1. What is an electrical transformer?

An electrical transformer is a machine that transfers electricity from circuit to circuit with a variable level of voltage without changing frequency. Today, they are designed to use alternating current, meaning that the fluctuation of current influences the source voltage fluctuation. So, increasing the current will increase the voltage and vice versa.


Transformers help improves the electrical system's safety and efficiency by raising and lowering voltage levels when needed. They are used in a wide range of civil and industrial applications, mainly and perhaps most important in the distribution and regulation of electricity over long distances.


2. Types of electrical transformers?


There are different types of transformers used in electrical systems for different purposes, such as the production, distribution, transmission and use of electricity.

Types of the transformer at MBT


Various types of transformers are Step up, Step down Transformer, Power Transformer, Distribution Transformer, Instrument Transformer including Current Transformer and Potential Transformer, Single and Three Phase Transformer, Autotransformers, etc.

3. Electrical transformer theory?


The coil to which the AC power is connected is called the primary coil and the coil connected with load is called the secondary coil. It only works with alternating currents because the alternating current induces each other between the two coil ends


When AC is supplied to the primary winding of voltage V1, an alternating flux is established in the core of the transformer, which is associated with the secondary winding and thus an emf is produced in it, called the Mutual Emf Induction. The direction of this induction is opposite to the applied voltage V1, due to Lenz's law


They are connected magnetically. Hence, the electrical power is transferred from the primary to the secondary through mutual inductance.


Emf induction in primary and secondary coils depends on the flux bond rate (N dϕ / dt).

dϕ / dt is the flux variation and is the same for both primary and secondary. Induction of E1 in the primary is proportional to the number of turns N1 of the primary (E1 ∞ N1). Similarly, the emf induced on the secondary coil is proportional to the secondary side's number of turns. (E2 ∞ N2).
