High Voltage Standard Capacitor
The YL series high-voltage standard capacitors (SF₆ insulated, 10–1800 kV) are primarily used in high-voltage laboratories. They can be paired with a bridge to measure dielectric loss and evaluate insulation condition, or serve as a voltage divider to replace standard voltage transformers for calibration and voltage measurement. For models rated above 800 kV, the standard capacitor, voltage divider, and partial discharge coupling capacitor are integrated into a single three-in-one independent parallel unit, significantly saving space.
The YL series gas-insulated high-voltage standard capacitors have a voltage range of 10 kV to 1800 kV and a capacitance range of 10 pF to 10,000 pF, with a dielectric loss (tan δ) of < 1×10⁻⁵.
