An Instrument for Measuring Electrical Field Strength in Strong High Frequency Fields

Abstract

An instrument is described which measures the intensity of the high frequency electric field, point by point, by means of the electrodeless discharge and a photoelectric device. The instrument is applicable to dosimetry and for local measurements in short wave therapy, but can also find application for investigation on insulators and other parts exposed to high voltage. The operation of the instrument and some examples of results obtained with the instrument are stated.
