One end of the primary of the isolation transformer is grounded earthed.
Electrical transformers types ppt.
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.
Step up and step down transformer.
A transformer is a static device which is use to convert high alternatic voltage to a low alternatic voltage and vice versa keeping the frequency same.
The comparison is shown in the figure below.
The coils are form wound but are multi layer disc type usually wound in the form of pancakes.
The transformers are classified based on voltage levels core medium used winding arrangements use and installation place etc.
The two electrical circuits are linked by mutual induction.
The various types of transformer shown in the figure above are explained in detail below.
The range includes oil filled transformers special purpose transformers and dry type transformers.
This type of transformer is categorized on the basis of a number of turns in the primary and secondary windings and the induced emf.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
