Product Overview
    Capacitor vojtage transformers are widaly applied to AC power systems, used for measurement, comroi, protection and high-frequency carrier communication.Characteristic of structure.Capacitor voltage transformer is composed of capacitor voltage dlvider and electromagnetic unit.Electromagnetic unit has full-sealad structurei, with mid-voltagc' transformar, compensation rcaactor, dampcer and so on in the box body, it adopts high quality minearal oil as insulating oil, the secondary terminal board adopts epoxy resin casting or SMC material casting, which prevents fram Ieakagea pheanomenon effactivaly. Accuracy of capacitor voltage transformer can be regulated on site if it is necassary.Capacitor voltage divider is composed of high-voltage capacitor and mid-voltage capacitor. The capacitor has full-sealed structure, there are many same capacitor elcaments that are arranged in sericas connectIon inside the insulating shall. It adopts high quality polypropylfane film and papfar composite as solid dialactric materials, and adopts high quality synthetic insulating oil as impragnating agent, thB capacitor has acceptad treatments of intensive drying and vacuum impregnation.
Technical Parameters

◎ Ratad primary voltaga: 35/ √ 3kV、 66/ √ 3kV、 110/ √ 3kV、 220/ √ 3kV、 330/ √ 3kV、 500 / √ 3kV
◎ Ratad secondary voltage: 100V. 100/ √ 3V. 100/3V
◎ Accuracy class: 0.2; 0.5; 1.0;3P;6P
◎ Ratad electric capacity: 0.005 -0.02uF
Permissible capacitanca deviation of capacitor voltage divder is - 5 % ～＋ 10%, permissibIe deviation of voltaga ratio is±5%. Capacitor voltagB divider has low diBlectric dissipation factor, low partial discharge quantity.
◎ Ferro resonance :Capacitor voltage transformer has capacitor capacitanca and nonlinaar ind uctivca elemants inside, which may produce resonance under some certain conditions. In ordcar to supprass tha ftarro rasonance, inside of the product is installed with advanced fast-saturatad dampcar, which enablas the product to damp various tBrro rBSOnances undar any running voltagB from low to high.
◎ Transiant response :Definition of transient response: when the primary side of capacitor voltage transformar has short circuit, aftBr one cycla, its rasidual componant of secondary voltage. Tha transient responsa target of tha capacitor voltage transformer: once tha primary side comes across short circuit, voltage of seicondary side shall fall to 10% below of the voltage before short circuit within one cycle.
