SF6 Gas Filled Standard Capacitors

SF6 Gas Filled Standard Capacitors

SF6 filled compressed-gas capacitors have proven in high-voltage technique as loss-free capacitance standards. Their capacitance is fairly independent of the voltage level, ambient temperature, proximity effects and place of installation. However, the most appreciated property of compressed-gas capacitors is their extremely small loss factor. Therefore, these capacitors are used as standard capacitors in bridge circuits for capacitance and tan measurements on all kinds of electrical apparatus and insulating media, for instance capacitors, cables, bushings support insulators, power transformers, instrument transformers, circuit breakers, switching rods, generators, plastics, insulating oil , etc.
