The different types of transformers are classified considering their objective, kind of cooling, size and potentials. The list is long, that is why electrical transformers market is considered one of the leading businesses in the world. Electrical transformers companies’ revenues are among the highest considering their market value. With this in mind, let us explore the main various kinds of electrical transformers.
This type of machines deal with high voltage grids. Notably these elements are gigantic in size. The installation of power transformers is held on power plants and transmission substation. For safety measures, high voltage flow cannot be delivered directly to facilities and building so, it has to be stepped down from high to medium. Later in another stage, it is going to be lowered more.
This type of transformer happens to be installed at the final phase of electrical journey. From the transmission phase to distribution, we certainly need a very peculiar kind of transformers. Moreover, delivering electrical energy to the consumer requires another stepped down level of voltage for safety measures. It is important to notice that electrical distribution transformers have various types.
Used mainly for safety reasons, these instrument transformers deliver constant rates during different conditions. These machines are sometimes labelled accurate ratio transformers. There are two varieties of instrument transformers. The first is called current instrument transformer. It is applied to determine AC voltage. That type works together with an ammeter. The second one is Potential instrument transformer. It has the same role as current type with slight differences. That type is working usually with a voltmeter.
A fixed machine that operates like any transformer following Faraday equation. It simply transmits AC energy from primary winding to secondary winding.
Three phase transformer:
This type of transformers relates to a connection between the three mentioned basic constituents. That makes this device a panel of networks. It compensates for single-phase transformers and it is less costly.
The functioning of this type of electrical transformers depends on uninterrupted winding that is appointed to one single side. It offers one task: either heightens or lowers the voltage. The difference between autotransformer and a two-winding transformer is considerable. The conventional transformer function in an isolated way however, the autotransformer windings are interrelated in the same magnetic field.
Surprisingly, this transformer does not convey the traditional role of other same devices. Isolation transformers do not decrease nor increase the voltage. This electrical equipment is rather a protective device. Their main role is to be an isolation tool of circuits. Note that it is essentially utilized to insulate conductors of electricity cables from the circuit load.
Smart grids are always a source of a great efficacious asset of energy management. A good energy management brings a reduction of consumption, a green ecosystem, and longer lifespan of electrical equipment. Smart transformers are a great help for not only voltage regulation (the traditional role) but also for data collection feedback. This data collection is an ultimate tool to prevent any electrical shortages and faults. This is thanks to its precise flow of information and its instant voltage optimization system.
