Standard capacitors

  • Application

    Standard capacitor is used in capacitance and tan δ measurement of capacitors, cables, bushings, insulators, etc. It could also be used as high voltage capacitor of electrical bridge, or as coupling capacitor in PD measurement.


    • Strong anti-jamming ability

    • High mechanical strength and good electrical performance

    • Special electrode makes the capacitance stable

    • Universal socket for capacitance measurement

    • Insulated by SF6 which is good at automatic-restoration, operation is reliable and safe
