AC high voltage ceramic capacitor are mainly used in AC voltage work situations, such as power testing equipment, national grid equipment, etc. AC high-voltage ceramic capacitors have high requirements for various indicators of the capacitor, and generally require the following parameters:
1. AC working voltage;
2. Lightning impulse voltage;
3. Partial discharge level;
4. Temperature change rate;
5. Higher frequency characteristics;
6. Loss tangent value;
7. Voltage linearity characteristics;
8. Over current capability;
9. Insulation resistance;
10. Leakage current;
The above indicators are necessary indicators for power companies to measure whether a capacitor meets the requirements. In addition, there are also various requirements such as size, encapsulation material, and appearance.
