A current generator is an essential piece of equipment in many industries, designed to produce consistent and controlled electric current for various applications.
The important role of insulating oil in equipment operation mainly includes the following aspects:
Insulation effect: Insulating oil has excellent insulation properties and can significantly improve the insulation strength of electrical equipment. In high-voltage electrical equipment, insulating oil can fill the gaps in solid insulating materials to prevent air or moisture from entering, ensuring reliable insulation of the equipment. Especially in solid insulation such as transformers, cables, capacitors, etc., insulating oil can impregnate and protect these equipment, prevent moisture intrusion, fill the gaps in the solid insulation material, and strengthen the insulation of the equipment.
The dielectric strength of transformer oil is also called the breakdown voltage (BDV) of transformer oil. The breakdown voltage is measured by observing the voltage at which spark lines are generated between two electrodes immersed in oil and separated by a specific gap. It is one of the items that must be tested during the daily maintenance of the transformer.
