Insulated Standard Capacitors is an Indispensable instrument in every modern high-voltage laboratory and test field where it occupies a wide range of important functions.

The SF6 insulated standard capacitor is used as Capacitance standard in measuring bridge Circuits to measure the dielectric dissipation Factor tanδ of all types including cables, capacitors, bushings, instrument transformers and power transformers. Further-more, It can be used as high-voltage capacitor for voltage divider circuits of high-voltage transformer test.

 The YL series standard capacitors can also be used as the high-voltage section of a capacitive divider. This allows high accurate voltage measurements e.g. such as those required for loss measurements on power transformer.

 For very high voltages a grad with discrete capacitor elements achieves a liner field distribution. These results in higher voltage withstand capability even at humidity levels up to 95% without condensation. We use special stainless steel to permit the prefect temperature and voltage coefficient stability.
