The dielectric breakdown strength of transformer oil is a critical parameter that indicates the oil’s ability to withstand electrical stress without failing. Typically, transformer oils should have a dielectric strength of at least 30 kV for a 2.5 mm gap under standard laboratory conditions. According to ASTM standards, regular testing of transformer oil for dielectric strength is essential to ensure its effectiveness as an insulator and coolant in electrical equipment. Globecore offers advanced testers for measuring the dielectric strength of industrial oils, providing accurate and reliable results in line with ASTM standards for oil analysis tests. Regular monitoring of this parameter helps in predicting the oil’s performance and longevity in transformers.
