Abstract

In a high voltage or current detector of the type utilizing an insulating tube, polarized light is directed to a photoelectric element mounted on the upper end or contained in the insulating tube so as to modulate the polarized light in accordance with the voltage or current to be measured. The modulated light is directed to a photosensitive element on the lower end of the tube for producing an electric signal which is applied to a meter for displaying the voltage or current.
