What is an oil BDV tester?

An oil BDV tester, or Breakdown Voltage Tester, is a specialized device used to measure the dielectric strength of insulating oils, such as those used in transformers and other electrical equipment. This tester assesses the oil’s ability to withstand electrical stress before breakdown occurs, ensuring reliable operation and safety in electrical applications. The testing process typically involves applying a controlled voltage to the oil sample until the dielectric breakdown occurs, allowing operators to determine the oil’s quality and effectiveness in insulating applications. Using an oil BDV tester is crucial for maintenance programs in industries relying on high-voltage equipment.
