What are the BDV test standards?

The BDV test, which stands for Breakdown Voltage Test, is crucial for assessing the dielectric strength of transformer oil, ensuring it meets required standards for safe operation in electrical systems. The primary standard for the BDV test is ASTM D1816, which outlines procedures for measuring the breakdown voltage of insulation oils. Additionally, IEC 60156 is an international standard that also details testing methods for the breakdown voltage of insulating liquids, ensuring consistency across different laboratories and applications. For accurate BDV test of transformer oil procedure, it is essential to follow these standards closely, including the setup of electrodes, sample preparation, and the environmental conditions during testing to obtain reliable and valid results.
