What is a BDV tester?

A BDV tester, or Breakdown Voltage tester, is a crucial device in the field of industrial oils used for measuring the dielectric strength of insulating liquids. Its primary function is to determine how well an oil can withstand voltage before it breaks down, indicating its ability to act as an insulator. This measurement is vital for ensuring the reliability and safety of electrical equipment that relies on such oils for insulation. The BDV tester works by applying a gradually increasing voltage to a sample of the oil until breakdown occurs, allowing users to gauge the oil’s effectiveness in preventing electrical failures. By regularly testing oils with a BDV tester, industries can maintain optimal equipment performance and prolong the lifespan of transformers and other electrical apparatus.
