The influence of the stability of the capacitance of compressed-gas capacitors by the contraction of the electric field

The phenomenon of voltage-induced capacitance fluctuations in some compressed-gas, high-voltage capacitors has been observed. The experimental results show that the contraction of the electric field at the part of the insulating housing near the lower end of the high-voltage electrode is probably the main cause of the phenomenon. For measurement requiring high stability, the working voltage must be decreased properly.<
