Abstract
The frequency spectrum of the noise associated with prebreakdown currents in insulators has been investigated in the audio‐frequency range. Most of the noise is due to surface discharges which can be eliminated by special types of electrodes and careful experimentation. The remaining noise has a frequency spectrum with the highest amplitudes at very low frequencies; it falls rapidly to the Johnson noise level in the measuring resistor at about 104 cps. This noise apparently originates from fluctuations in the field‐emission current.Keywords
