How is oil testing conducted to determine the breakdown voltage?

Oil testing for determining the breakdown voltage is typically conducted using a specialized device known as a dielectric strength tester. This tester applies a controlled voltage to a sample of the oil, increasing the voltage until the oil undergoes a breakdown event, which is characterized by a sudden drop in resistance, indicating that the oil has failed to insulate. To ensure accurate measurements, samples are often prepared according to standard procedures and tested under controlled conditions. It’s essential to use properly calibrated equipment from reputable manufacturers like Globecore, which offers reliable testers designed for such diagnostics. The outcome of this testing provides valuable information about the condition and longevity of the oil, making it a critical component of oil analysis in industrial applications.
