The Automatic Oil Dielectric Strength Tester is designed for safe testing of large power transformers and other high-voltage electrical equipment including oil circuit breakers, oil-filled cables, power capacitors, and oil sleeves.
During operation, transformer oil performance gradually deteriorates due to exposure to oxygen, high temperature, humidity, sunlight, strong electric fields, and impurities, compromising its insulation capabilities. This tester accurately identifies performance degradation, as insulation oil quality is directly related to breakdown voltage.
