Bdv test of transformer oil procedure pdf file

Product Information Dissolved gas analysis and supervision of oil condition in transformers and reactors Transformers Diagnostic Services at ABB performs dissolved gas analysis and supervision of oil condition in power transformers, reactors, instrument transformers, circuit breakers and oil-insulated cables.

Transformer Insulating Oil Test Methods (ASTM) Transformer Insulating Oil Test Methods (ASTM) Measures the electrical insulating properties of transformer oil under conditions comparable to those of the test. A low resistivity reflects a high content of free ions and ion-forming particles in Dear All, We have tested the BDV of a new 33KV / 11KV, 37.5MVA Transformer. We have recorded the readings as below. The test was repeated 5 times on the same sample of Transformer oil with a time gap of 5 minutes. Higher the moisture in the oil, lower will be the BDV for transformer oil. BDV of 50 kV and above is considered good for operation while 60kV and above means the oil is in excellent condition (when gap between terminal during BDV test is 2.5 mm). In this topic, I will inform you about bdv test of transformer oil. It is also known as dielectric strength of transformer oil. Vector group test of transformer || Testing of transformer | BDV TEST PROCEDURE . B.D.V. TEST FOR TRANSFORMER OIL. The dielectric strength of an oil still ranks as the most common field test. The significance of the test it will detect free water, dirt and conductive particles. For the purpose of BDV test, oil sample from Transformer is taken in a Sample Bottle. While taking sample of oil from transformer, Sample bottle should be flushed well by Transformer oil and oil in Sample bottle should be vented properly so that atmospheric moisture could not ingress in the sample oil. The laboratories test for transformer oil purity, quality, and chemical composition. Transformer oil test methods include ASTM, BS,and other recognized transformer oil analysis testing procedures.
