Electric field detector

摘要

Apparatus for detecting electric fields and providing an indication of their magnitude includes a glass bulb containing a gas such as neon. When the bulb is placed in a time varying electric field, pulses of electromagnetic radiation are generated within the bulb. The number of pulses is proportional to the magnitude of the variation in the electric field. The pulses are transmitted by a fibre optic bundle to detection and recording apparatus to provide an indication of the magnitude.
