What does the BDV test value indicate?

The BDV test value, or Breakdown Voltage test value, is a critical measurement indicating the electrical insulating properties of industrial oils. It reflects the oil’s ability to withstand voltage before breakdown occurs, which is essential for ensuring the reliability and safety of electrical equipment insulated by these oils. A higher BDV test value signifies better insulating characteristics, thereby preventing electrical failures and prolonging the lifespan of transformers and other electrical apparatus. Regular monitoring of the BDV test value helps in assessing oil degradation and determining the need for oil replacement or treatment.
