The topic of the sixth lesson are:
- Breakdown voltage tests, history, methods, procedures, and clarifications
Marius Grisaru’s course on insulating liquid tests focuses on the breakdown voltage (BDV) test, crucial for transformer health. BDV is sensitive to moisture, particles, and temperature, indicating insulation risk. Key standards include ASTM D877, ASTM D1816, and IEC 60156, each with specific applications and sensitivities. BDV is affected by temperature, moisture, and oil flow, with significant variations at different conditions. The test’s reliability depends on proper preparation, equipment calibration, and adherence to standards. The course emphasizes the importance of trending BDV over time to predict maintenance needs and avoid false security.
