What is the formula for BDV testing of transformer oil?

The BDV test for transformer oil, or Breakdown Voltage test, is not represented by a specific formula but rather conducted using specialized equipment designed to measure the breakdown voltage of the oil sample. The process involves placing the oil between two electrodes and applying an increasing voltage until a dielectric breakdown occurs. The maximum voltage at which the oil maintains its insulating properties, without conducting electricity, is recorded as the BDV result. This measurement is critical for assessing the quality and insulating capability of transformer oil, ensuring it meets operational standards for safety and efficiency. Globecore offers advanced devices for BDV testing that provide accurate and reliable results for transformer oils.
