A lighting transformer is a electrical device that is used in order to transport electric energy from one place to another. In other words, a lighting transformer is used to move electrical energy from one electric circuit to another.
This is done by using electrical conductors which are arranged such that they are inductively coupled. Let us take a look at the working of lighting transformers to be able to understand them better. Initially, a deviation in the electric current in the first circuit leads to a change in the magnetic field.
This change in the magnetic field leads to an alteration in the voltage of the second electric circuit. In order to further the flow in the transformer one can add another change of load to the current in the second circuit. In this manner, a change in every electric circuit gives birth to an electric change in the subsequent circuit. Hence, electrical energy can be said to be transported by the principle of mutual induction.
Light transformers are some of the most efficient and effective electric devices as they are known to successfully transfer 99.75% of the total energy input to the output junction.
Transformers come in a variety of sizes that can range from minute, button sized devices to huge equipment weighing hundreds of tons. Lighting transformers are extremely useful due to their increased efficiency and effectiveness.
Lighting transformers are used to augment the levels of voltage in a circuit prior to transferring the electrical energy through electric cables over long distances. The working of a light transformer can be understood to be based upon two fundamental principles. The first principle is the one dealing with the fact that electric current can be used to create a magnetic field.
This is the principle of electromagnetism. The second principle that is used is the one of electromagnetic induction which states that an alteration in the magnetic field inside a coil of wires results in the creation and transfer of voltage across the ends of the coil. Transformers are classified on the basis of certain characteristics. In detail, they are categorized on the basis of the application function, the type of cooling being utilized, the end purpose of the device, the level of power being utilized and the range of the frequency. Lighting transformers in order to achieve the ideal levels of efficiency need to have no energy losses. In other words, they should be 100% efficient. As 100% efficiency is not completely possible, it is important to maximize as much effectiveness as possible. Hence, in properly created lighting transformers, the energy is distributed in the core, the windings and the surrounding structure. The loss of energy varies with the load of the current. In a simple transformer, the change in current across the primary coil results in a magnetic field. The primary coil along with the secondary coil is wound around a core. The core is created from a material which has high magnetic permeability. Due to the excess magnetic nature of the core, the electric current generated by the primary coil is passed to the core through the magnetic field and from the core it is transferred to the secondary coil.
