How is transformer oil BDV testing conducted?

Transformer oil BDV (Breakdown Voltage) testing is conducted using a specially designed oil BDV test kit. The process generally involves collecting a sample of transformer oil, ensuring it is free from moisture and contaminants, and then placing the oil in a testing cup of the BDV tester. The device generates a controlled electrical field in the oil, gradually increasing the voltage until a discharge occurs. The voltage at which the breakdown occurs is recorded as the BDV value. This measurement is crucial for assessing the insulating properties of the oil, helping to determine its ability to withstand electrical stress. Globecore manufactures high-quality oil BDV test kits that can accurately measure the breakdown voltage of transformer oils, ensuring reliable results for maintenance and monitoring purposes. Remember, regularly testing the BDV value of transformer oil is essential for the longevity and safety of electrical systems.
