The dielectric breakdown voltage test oil is conducted using specialized equipment designed for measuring the dielectric strength of insulating oils. The process involves preparing a sample of the oil and placing it in a test cell, typically consisting of two electrodes. The electrodes are then separated by a specific gap distance, which is crucial for the accuracy of the measurement. The test device gradually increases the voltage until breakdown occurs, meaning that an electric current starts to flow through the oil, leading to its failure as an insulator. The maximum voltage reached before this breakdown is recorded as the dielectric breakdown voltage, providing essential insights into the oil’s insulating properties and overall quality. It is important to conduct this test under controlled conditions to ensure reliable and reproducible results.
