Abstract :
This paper describes the properties, characteristics, and uses of the vacuum capacitor. The constructional details of two General Electric vacuum capacitors, the GL-1L38 and the GL-1L22, are discussed. Design considerations are discussed from the viewpoint of both the designer and the manufacturer. Capacitance formulas are given, and the equation for energy loss is derived. Operating characteristics and ratings of the vacuum capacitor are considered, and the effects of humidity, temperature, and vibration are noted. The advantages of the vacuum capacitor are thoroughly discussed and the applications which are brought about because of these advantages are described.
