A Double Frequency Method for the Determination of the Voltage Dependent Capacitance Variation of Compressed Gas Capacitors

This paper describes the development of a double frequency measurement method by the aid of which the voltage dependent capacitance variation of high voltage compressed gas capacitors is determined with most methodical exactitude. The measurement method makes use of a modified Schering-bridge and of a specially developed tuning device for bridge balancing, the selectivity of which is extremely high, and new in the range of low frequency measurement technique.
