All That You Should Know About Electrical Transformer

Posted by Admin on September, 23, 2013

Electrical Transformer is a technologically advanced mechanism that transforms current voltage from particular circuit to other electric circuit via electromagnetic induction. It increases or decreases the voltage that comes from the substation. By and large, the Electrical Transformers, also known as Power Transformers, are used to convey current from power plants to commercial as well as residential places.

The Categorization:

On the whole, Electrical or Power Transformer is a liquid filled unit that can be classified into 3 size categories, that is, small power (below 10 MVA), medium power (from 10 to 50 MVA), and large power (above 50 MVA). Though this categorization is not recognized by CSA, ANSI or IEEE, however, most of the times, is referred to by the consultants and manufacturers.

Service Life Of Electrical Transformer:

A typical Electrical Transformer’s life expectancy can be determined by a number of factors, the primary of which being the excellence of its insulation system after certain period of time. Elaborating further, the oil used in Electrical Transformer is mostly subject to moisture and in the presence of even very less amount of water the transformer’s insulating value gets acutely reduced. Apart from this, the oil’s performance as a cooling medium as well as insulating quality can be reduced by oxidization too. It is, hence, very crucial that the structure and the design of Electrical Transformer is such that it slows down the contact of insulation system to the external environment that is full of both oxygen and moisture. Nevertheless, any typical Power Transformer comes with a substantial life cycle of around 30 years and it not at all means that the transformer cannot be used beyond this duration.


Undoubtedly, Electrical Transformers are the heart of every electrical distribution and transmission system. In order to ensure that the Electrical Transformer operates with maximum security, it is prudent to check that it works as per the specific overload capacity and limit load. Also, the Electrical Transformer must be checked on a regular basis so as to avoid unexpected power-related incidents.
