Product Description

                                                                                            STANDARD CAPACITOR 

High-Voltage standard capacitor is a gas-insulated precision device mainly used for measuring capacitance and dielectric loss factor in high-voltage scenarios, and it can also serve as a high-voltage reference unit for capacitive dividers. It features an extremely low loss factor, excellent capacitance stability, and is unaffected by external electric fields—even in high-humidity environments, it can maintain reliable voltage performance. Additionally, the device supports professional laboratory calibration, is compatible with various modern loss factor measuring instruments, and provides an accurate reference for power testing, industrial inspection, and other scenarios.
