The BDV test means that the breakdown voltage of transformer oil is measured to assess its insulation properties and reliability. This test is performed using a specially designed device known as a dielectric strength tester. During the BDV test, a sample of transformer oil is placed between two electrodes, and an increasing voltage is applied. The point at which the oil fails and allows current to pass between the electrodes is recorded as the breakdown voltage. This measurement is critical for evaluating the quality and condition of the oil, as it provides insights into the presence of moisture, contaminants, and overall degradation. For accurate results, it’s essential to follow standardized procedures like ASTM D1816 or IEC 60156. Globecore offers reliable testers designed for these purposes, ensuring precise and consistent BDV test results for transformer oils.
