What is the BDV test of transformer oil?

The BDV test of transformer oil, also known as breakdown voltage testing, is a crucial diagnostic procedure used to assess the electrical insulating properties of transformer oil. This test measures the voltage at which the oil breaks down and conducts electricity, indicating its ability to insulate electrical components in transformers. A high BDV value suggests good insulation quality, while a low value may indicate contamination or deterioration of the oil. Globecore offers advanced testers specifically designed for conducting BDV tests, which provide accurate and reliable measurements to ensure the safe and efficient operation of transformers. Regular BDV testing is essential for maintaining transformer reliability and preventing electrical failures.
