YL Series High Voltage Standard Capacitor（10-1800kV）

YL series High Voltage Standard Capacitor is a stable SF6 gas-insulated standard capacitor with the voltage range from 10kV to 18000kV. Those HV and UHV test labs widely use it with the measuring bridge or the tg delta measurement device so as to measure the technical data of the test objects in the accurate way, including capacitance, tg delta value, power factor, voltage, frequency etc.. While these data are very important for the insulation evaluation upon the capacitive test object such as cable, bushing, instrument transformer, capacitor etc. Furthermore, YL series HV standard capacitor can also work with the high accurate current transformer to measure the inductance and loss of those reactors which have low power factor.

YL series High Voltage Standard Capacitor can be the HV arm for a capacitive voltage divider. Its good temperature coefficient and voltage coefficient ensures its high accuracy in the voltage measurement. With an electronic LV arm, YL capacitor can replace the standard potential transformer from 10kV to 1000kV for the calibration of angle error and ratio error upon the potential transformer. Moreover, it can do accurate voltage measurement for the HV output of transformer.

The YL series capacitor (800kV class above ) has three independent capacitors in parallel, C1 (300pF), C2 (20pF) + QND standard voltage divider, and C3 (500pF~1000pF) coupling capacitor which is used for partial discharge test. These three capacitors are working independently, which is a good choice to replace the coupling capacitor in the traditional HV test system so as to save a lot of space for a normal AC test system in the HV lab.
