Product descriptions
An oil-immersed test transformer with no partial discharge is a test transformer that exhibits no partial discharge or only minimal partial discharge. It is suitable for conducting partial discharge tests and power frequency withstand voltage tests on various electrical equipment, electrical components, and insulating materials. Oil-immersed partial discharge-free test transformers are widely used by manufacturers of electrical appliances, cables, motors, transformers, current transformers, insulating materials, and related high-voltage components, as well as in high-voltage testing laboratories at power utilities, research institutions, and universities, to conduct partial discharge and power frequency withstand voltage tests on their products.
Features & Advantages
- An oil-filled epoxy cylinder design, offering low partial discharge and minimal waveform distortion.
- Low-impedance voltage, exceeding national standards
- Multi-layer shielding for strong interference resistance
- High insulation rating, with partial discharge ≤5 pC
- Equipped with an automatic protection device, providing reliable overcurrent and overvoltage protection
