Genneal Information:
Compressed air standard capacitor is a necessary instrument in every HV test lab. It is used to measure the capacitance of capacitor, cable, sleeve, insulator, transformer winding, and insulating material, as well as tanδ of dielectric loss. At the same time, it can also be used as HV capacitor for pressure sharing device of HV measuring capacitor. Under certain condition, it can be used as HV coupling capacitor during partial discharge measurement.
Performance
Standard capacitor is used as comparison reference, which is assorted to precise measurement to inductance value, loss, capacitance, and dielectric loss value of HV equipment such as reactor,cable, transformer, sleeve, and capacitors etc. The standard capacitor is equipped with HV pole which can be connected with other HV parts in HV measuring circuit without partial discharge.
Standard capacitor is designed for indoor application, movable.
For extra high voltage, discrete capacitor grading is used to realize linear distribution of electric field,
so as to maintain an ambient humidity above 95% (without condensate water). Standard capacitor
has high voltage endurance and extremely stable humidity and voltage factor.
The sf6 gas insulated standard capacitor is used together with a c and tan delta measuring bridge as the comparison standard leg of the bridge. It is used as capacitance standard in measuring bridge circuits to measure the dielectric dissipation factor tan-delta, further-more, it can be used as high-voltage capacitor for voltage divider circuits of high-voltage transformer test. Highest long-term stability is guaranteed and proven over 20 years. A wide range of different sizes, values and voltage ranges are available. We can produce 5kv~1600kv. We can also provide the professional solutions and equipments for: withstanding voltage testing, c & tan-delta (power factor) testing, partial discharge (pd) testing and impulse voltage testing.
