Concept and Usage of Oil Immersed Power Transformers

1. Concept and Usage of Oil Immersed Power Transformers Presented By: http://www.farady-electric.com

2. 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

3. 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 transformeruse 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.

5. 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. www.farady-electric.com is one the professional transformer manufacturer.
