Abstract
A measurement device for operating in high voltage electrical fields such in high voltage electrical switchgear, having a sensor and a λ/2 monopole helical antenna coupled thereto. The antenna is coupled to a ground via return stub in lieu of the common ground plane. The antenna is made of wire having a sufficiently large diameter to prevent forming corona discharge point electrode throughout the outer surface of the volume defined by the antenna, thus minimizing corona discharge risk. The antenna further provide relative immunity from induced voltage at the 50-400 Hz range from the high voltage fields, allowing ESD sensitive devices to operate in close proximity to the high voltage conductors.
