Transformer oil bdv test procedure

The transformer oil is filled in the vessel of the testing device. A test voltage is applied to the electrodes and is continuously increased up to the breakdown . BDV means break-down voltage, also named as Dielectric Strength Valve. BDV Test is an very important testing procedure for the insulation oils in transformer.

Dielectric strength of transformer oil is also known as breakdown voltage of transformer oil or BDV of transformer oil.

Break down voltage is measured by observing at what voltage, sparking strants between two electrods immerged in the oil, separated by specific .

BDV test means Breakdown Voltage Test.

In transformer oil has mainly two purposes, first . What are the methods for testing oil ? This paper reviews some of the transformer oil tests and there significance. Water, in minute quantities, is harmful in power equipment because it is attracted to . To assess the insulating property of dielectric transformer oil , a sample of the transformer oil is taken and its breakdown voltage is measured. The lower the resulting breakdown voltage, the poorer the quality of the transformer oil.

Transformer Oil Breakdown voltage testing procedure.

From my experience, untreate raw transformer oil has to withstand kV per 2. Most of the stated tests on transformer oil are carried out at different testing laboratories or . The laboratories test for transformer oil purity, quality, and chemical composition. Specific transformer oil test method availability will vary depending upon location. Please contact Intertek for more information.

Test the quality of the dielectric oil of your transformers on-site! Insulating oil of transformers and current transformers fulfills the purpose of insulating as well as cooling. Preparing solid asset maintenance plans.

Maintenance costs are found to be heavy burden on utilities. Other tests are conducted to enhance the diagnosis reliability of the megger test : Oil Breakdown Voltage ( BDV ). Tests that are concerned with the immediate condition and acceptability of the insulating oil include dielectric breakdown tests , moisture measurement by the Karl Fischer (KF) method , and dielectric dissipation factor. Megger provides laboratory grade oil test equipment, backed by experience reaching back to the early 20th .
