Medium Voltage air reference capacitor used for very accurate measurement of capacitance and dielectric dissipation factor (Tan d) mostly in laboratories:

- Voltage range 500 V to 5 kV - Tangente delta (Tan d) = or < 1.10-5 - Nominal capacitance 10 pF to 10 nF - Voltage coefficient < 30 ppm or < 3 ppm - Stability / year < 0,05 % or < 3 ppm
