Product Description

0-80kV Transformer Oil Test Equipment Oil Dielectric Strength Tester with High Quality

Transformer Oil Types

There are two main types of transformer oil used in transformers:

1. Paraffin based transformer oil
2. Naphtha based transformer oil

Naphtha oil is more easily oxidized than paraffin oil. But the product of oxidation - i.e. sludge - in the naphtha oil is more soluble than the sludge from the paraffin oil. Thus sludge of naphtha-based oil is not precipitated in the bottom of the transformer. Hence it does not obstruct convection circulation of the oil, means it does not disturb the transformer cooling system.

Although Paraffin oil has a lower oxidation rate than Naphtha oil, the oxidation product (sludge) is insoluble and precipitated at the bottom of the tank. This sludge acts as an obstruction to the transformer cooling system.

Another problem with paraffin-based oil that the dissolved waxes inside of it can lead to a high pour point. Although this is not an issue in warmer climate conditions (such as India).

Despite the disadvantages mentioned above, paraffin-based oil is still commonly used in many countries (such as India) due to its high availability.
