As we know, transformers are the storage device
for electricity that transforms electric circuit
from one place to other. This beautiful concept
was discovered by Michael Faraday and Joseph
Henry in 1831. Basing on the power capacity,
frequency range, voltage class, cooling type,
application, purpose and by its winding turns
transformers are classified into different types
such as

• Amorphous Core Transformer
• Conservator Type Oil Transformer
• Gilled Radiator Step Up Transformer
• Hermetically Sealed Distribution Transformer
• Onload Tap Changer Distribution Transformer
• Wound Core Distibution Transformer

One of the most important characteristic of
transformers is that it dissipates more heat
energy and it needs to be cooled in an efficient
way, otherwise it would destroy the insulation of
the transformer. Basing on the cooling mechanism
adopted, transformers are broadly classified into
two types i.e 1. Dry type transformer 2. Liquid
filled or oil immersed transformers. These oil
immersed power transformer use mineral-based oil
and cellulose paper in their insulation systems.
This combination exhibits proper thermal and
dielectric properties. This option is also
relatively cheaper than the other options. But
one negative point of such transformer is its
flammability. This is the reason why, oil
transformer are usually restricted to outdoor
installations.

Cast resin transformer is otherwise known as dry
type transformer. Basically, dry type transformer
construction uses high-temperature insulation
that exceeds the ratings of cellulose or 'O' and
'K' class fluids. These transformers have been
used effectively in diverse commercial and
industrial environments. The most advantageous
point is that reduced fire risks. These
transformers have been used successfully in
special applications where the public are in
close proximity, such as underground tunnels,
residential apartments, oil rigs etc.
