  • Capacitance - All Manufacturers - eTesters.com

    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.
