How does a BDV test kit work?

A BDV test kit, or Breakdown Voltage test kit, is designed to assess the dielectric strength of insulating oils used in electrical equipment. The kit operates by measuring the voltage at which an electrical breakdown occurs in a sample of oil. To perform the test, the oil sample is placed in a test cell, where two electrodes are submerged in the fluid. The BDV test kit then progressively increases the voltage between the electrodes until the oil breaks down, allowing current to pass through. This breakdown voltage is recorded as a critical parameter indicating the oil’s insulating properties and its ability to withstand electrical stress. Utilizing a BDV test kit can help ensure the reliability and safety of electrical systems by determining the dielectric strength of industrial oils employed in transformers, capacitors, and other electrical devices.
