Specific gravity directly affects heat transfer. If the oil is heated, its specific weight decreases, and vise versa when the oil is cold. - Transformer oil of … Mineral Oil is considered as a top choice in outdoor installations where low cost and flammable nature is understood and accepted. Transformer Oil – What is it, and why sample? The specific gravity of a liquid does not alter the centrifugal pump curve at all. Water has a specific gravity of 1.000; transformer oil is lighter than water, so the specific gravity is less than one. Special testing of transformer oil: This types of testing mainly used under the physical and chemical industry. While, it is used extremely cold climates, specific gravity, physical and chemical reaction. The specifications for all oil is different between each manufacturer, but they are all relatively the same when comparing the same oil types. {�E��aq:�2��� �1П�N��i�; ]�hq� �CF4��3��� �U[�_R�o3�Rx� �!��9�j� �O�e���E�P�Ae,DsX������;�$��� 0000048676 00000 n Specific gravity directly affects heat transfer. The following tests can be adopted before using the insulating oil.

As a result, the insulation system can last up to three times longer than in a mineral oil filled transformer. We are based in the Washington, DC Metropolitan Area and are prepared to respond to any electrical emergency or need you may have. If you have to install a transformer in the basement of a building, 3 floors underground, you may decide you want a higher flash point depending if it is occupied office space. Ageing and oxidation of the oil tend to increase viscosity. Base oils - true to their name - are the basis for a variety of products. Larger transformers in secured locations (behind a security fence) will have a valve on the bottom of the tank that is readily accessible. Specific gravity of diesel fuel oil is a comparison of its density with that of pure water. The oil test in which spark occurs and the testing set trips is known as transformer oil dielectric strength test.This test is performed in the oil testing set. 0000002518 00000 n General Electric Multilin Protective Relaying, Electromechanical Relay – Basic Operation, https://powertransformerhealth.blogspot.com/p/analysis-of-dga.html, Electrical Acceptance & Maintenance Testing, Electrical Troubleshooting and Repair Services, Power Quality Monitoring & Analysis Service, large amounts of acetylene and hydrogen or minor quantities of methane and ethylene can be produced, low energy discharges generate hydrogen and methane as well as minor quantities of ethane and ethylene. The Density (Specific Gravity) of the oil is the ratio of the weights of equal volumes of oil and water. 0000057910 00000 n A high specific gravity indicates the oil's ability to suspend water. You need to take your sample from the top. As the temperature expands, the density of the oil diminishes. You can also get free analysis of dissolved gases from this link.

In the dielectric strength test of transformer oil, the test voltage should be raised to the specified value (or the breakdown voltage if it is less) at a uniform rate in 10-15 seconds and maintain for a one minute.Preliminary arcing should be ignored. If the oil has a specific gravity >1, this means the oil will settle to the bottom and any water or moisture will sit on top. In extremely cold climates, specific gravity can be used to determine whether ice will float on the oil.
