Why the voltage of Oil BDV tester set 100KV?

Transformer oil plays important role to make sure the proper functioning and longevity of transformers. Testing the breakdown voltage, also known as the oil BDV test is one of key aspects of maintaining the quality of transformer oil.
The voltage of oil BDV tester is typically set at 100KV. There are several reasons for this specific voltage level. Firstly, the voltage 100KV is considered to be an industry standard for testing transformer oil. This level of test voltage provides a reliable and consistent measurement of the oil's dielectric strength, It is essential for determining its ability to withstand electrical stress.
Secondly, the test voltage of 100KV allows for accurate and precise measurements of the oil's breakdown voltage. Through subjecting the oil to this level of voltage, any potential weaknesses or contaminants present in the oil can be quickly identified. This information is critical for diagnosing potential issues with the transformer and taking corrective actions to prevent equipment failure.
Furthermore, using test voltage of 100KV ensures that the oil BDV test is conducted in a safe and controlled manner. This voltage level is high enough to effectively assess the oil's dielectric strength, but not so high as to pose a risk to the tester or the equipment being tested.
Therefore, the choice of a 100KV voltage for oil BDV testing is based on industry standards, accuracy of measurement, safety considerations, and the ability to detect potential issues with transformer oil. Through consistently testing transformer oil at this voltage level, maintenance professionals can make sure the reliability and longevity of transformers. Our oil BDV tester can be up 100KV with single oil cup or three oil cup, complying to many standards like IEC standard and ASTM standard. They can totally meet the test requirement for oil dielectric strength test.
