Capacitive voltage dividers are essential for high-voltage measurements (power frequency, pulse, and lightning impulse). Their accuracy depends on the stability and linearity of the high-voltage arm capacitance. Our high-voltage doorknob capacitors feature:
- Temperature-compensated ceramic dielectrics
- Capacitance change rate <±0.5%
- Voltage coefficient deviation ≤±0.2% (-40°C to +85°C)
- Long-term stability for voltage dividers
- Low loss (tanδ ≤ 0.001)
- High insulation resistance (≥105 MΩ)
For example, in 500kV series resonant test equipment, the voltage divider maintains Class 0.2 accuracy (error ≤±0.2%) in the 150kV-300kV range. Our capacitors effectively suppress measurement errors caused by DC leakage current and dielectric polarization.
