    The cornerstone of measurement: the accuracy contribution of doorknob capacitors in capacitive voltage dividers.
    Capacitive voltage dividers are core equipment for high-voltage measurements (power frequency, pulse, and lightning impulse). Their accuracy directly depends on the stability and linearity of the high-voltage arm capacitance. High-voltage doorknob capacitors utilize temperature-compensated ceramic dielectrics, offering a capacitance change rate of <±0.5% and a voltage coefficient deviation of ≤±0.2% within the temperature range of -40°C to +85°C, providing the voltage divider with long-term stability. For example, in 500kV series resonant test equipment, the voltage divider must maintain Class 0.2 accuracy (error ≤±0.2%) in the 150kV–300kV range. The low loss (tanδ ≤ 0.001) and high insulation resistance (≥10^5 MΩ) of doorknob capacitors effectively suppress measurement errors caused by DC leakage current and dielectric polarization.
