<p>PURPOSE:To obtain a portable photoelectric device for measuring a voltage which can measure the voltage in an arbitrary place of an electric apparatus, a high-voltage apparatus in particular an electric wire, etc., and also secures sufficiently the safety of an operator at the time of a measuring operation. CONSTITUTION:When an operator measures the voltage of a high-voltage apparatus, an electric wire or the like which is an object of measurement, a grounding conductor 7 is connected to a low-voltage electrode, a sensor part 3 of a photoelectric device for measuring the voltage is supported by a supporting pipe or a supporting rod 8 or the like and a measuring terminal 1 is brought into contact with an arbitrary place of measurement or connected thereto. Thereby an electric field is impressed on photoelectric voltage sensor elements 3a...3e of the sensor part 3 and the strength of light received in a measuring part 9 changes. The measuring part 9 converts the strength of light into an electric signal and displays it or outputs it as the electric signal. Since the measuring terminal 1 can be replaced, besides, the operator can employ the measuring terminal 1 in a shape being most suitable for the place of measurement.</p> |
