Zusammenfassung:The invention relates to an electrostatic device for measuring high electrical voltages in electrical and energy equipment and in radiological and radiotherapeutic medical equipment. According to the invention, the device is made in such a way that the direct or alternating voltage to be measured is applied by means of an input terminal (4), insulated with teflon (5) from the ground (14) of the device, to a disk-shaped copper electrode (3) placed in a sealed polypropylene tube (I), with removable side covers and glass window (1), the electrode (3) producing a uniform electric field in the lines of which an optical indicator element (8) slides, said element consisting of a low-pressure neon discharge tube connected to the ground (14) of the device, positioned at the end of a sliding rod (7) coaxial with the disk-shaped electrode (3), until the neon tube emits a red-orange color, i.e. when it is in an area of the electric field with a sufficiently high intensity to generate a luminescent discharge, so that, after reading the distance D on a graduated ruler (10), by means of an indicator needle (11) rigidly fixed on the sliding rod (7), and based on a calibration curve established when the device was put into operation, the applied electrical voltage can be estimated.
