Product Description

GDSC-200kV/100pF Standard Capacitor for tan delta testing

Product Description

In every high-voltage laboratory and test, compressed gas standard capacitor is an important instrument, in these occasions, it plays a very important role. In the dielectric loss test, compressed gas capacitors are used to measure the capacitance and dielectric loss tangent (tgδ) of capacitors, cables, bushings, insulators, transformer windings and insulating materials. Moreover, it can also be used as a voltage divider in high voltage measurement. Under certain conditions, it can also be used as a high-voltage coupling capacitor in partial discharge measurement.

II. Features
 

1. The capacitance (C) and dielectric loss (tgδ) are extremely stable.
2. The influence of changes in air pressure, temperature and humidity on the capacitance is small and can be ignored.
3. The dielectric loss of itself is small.

III. Structure
 

1. The shell is composed of an insulating sleeve and a bottom and cover made of steel plate. The bottom and cover are fastened at both ends of the insulating sleeve with bolts and rings. The upper and lower ends of the capacitor are provided with anti corona covers.
2. The capacitor shell is equipped with coaxial, highly polished cylindrical high and low voltage electrodes.
3. The capacitor is equipped with a pressure gauge and an air valve for observing the internal pressure and charging and discharging.
4. The capacitor is filled with SF6, and the external shielded socket can be used with all kinds of bridges and plugs of all kinds of automatic dielectric loss meters at home and abroad
