Transformer Insulating Oil Density

Act as a coolant.

Transformer insulating oil density. Because we offer three different ester fluids our customers can choose the one that best suits their specific installation and performance criteria. A high specific gravity indicates the oil s ability to suspend water. Density of transformer oil at 29 5oc is 0 89g cm3 the exact density of transformer oil depends upon the manufacturer but expressed in si units is typically a little less than 900 kg m3 at 20oc. The specific gravity is of an insulating liquid is simply the ratio of the density of the fluid to the density of water.

Analyzing transformer insulating fluid. Electrical transformers need an adequate insulation. Low voltage strip can be bare with paper insulation between layers. The specific density of transformer oil will vary based on the manufacturer and region or location where the oil will be primarily used.

Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. One of the most important components of insulation system is transformer insulating oil. Astm d1298 the specific gravity relative density of an oil is the ratio of the weights of equal volumes of oil and water. Transformer oil also known as insulating oil is a special type of oil which has excellent electrical insulating properties and is stable at high temperatures.

In extremely cold climates specific gravity can be used to determine whether ice resulting from freezing. It is a fluid or liquid substance that is common for transformer system and known as the most popular insulating material all over the world. The only treatment is oil change and reclamation of old oil or in situ regeneration. Even low levels of oxidation of the transformer s oil will reduce the life of its cellulose insulation.

It is therefore important to pay close attention to oil density when filling or re filling your electric power transformers with dielectric insulating oil. Transformer oil is used in oil filled electrical power transformers to insulate stop arcing and corona discharge and to dissipate the heat of the transformer i e. The midel range of ester transformer fluids delivers an array of distinct benefits when used in a power transformer or distribution unit. One major element of a transformer maintenance program is periodic testing of its insulating fluid and obtaining a good fluid sample starts with knowing where to draw the sample from.
