Standard Capacitors

Compressed gas insulated high precision capacitors for C/tan delta measurement, or very accurate voltage measurement



Gas insulated standard capacitors are used for high voltage measurements of capacitance and loss factor, as a reference normal. They can also be used as a very accurate HV section of a capacitive voltage divider. The standard version is for indoor use, however a special outdoor design is available upon request. Mohaupt standard capacitors can be used in combination with any kind of modern loss factor measurement equipment.


  • Extremely low loss factor and high stability of capacitance
  • Unaffected by external field influences (proximity effects)
  • Excellent voltage performance even under high humidity conditions
  • Calibration at certified laboratory available upon request
