Title:
METHOD AND APPARATUS FOR VOLTAGE DETECTION IN DISTRIBUTION LINE
Document Type and Number:
Japanese Patent JP2003337144
Kind Code:
A
Abstract:

To provide a voltage detection apparatus whose operability is enhanced and whose safety is ensured by a method wherein a voltage is detected in a centralized administration manner in a place separated from a narrow voltage detection place without going to the voltage detection place in a voltage detection operation in a distribution line.

The voltage detection apparatus 10 is provided with a detecting electrode 13 in an electrostatic coupling state with respect to an electrical conductor 11 embedded in an insulation part 12; and a grounding body 15 arranged in a state surrounding an outer circumferential part of the insulating part 13. When whether the voltage is applied to the electrical conductor 11 in the distribution line with the installed voltage detection apparatus 10 is discriminated, a capacitor 21 is arranged across the detecting electrode 13 and the grounding body 15, a terminal 22a of a conductor 22 connected to the detecting electrode 13 is arranged in a separated specific place, a voltage detector D is brought into contact with the terminal 22a of the conductor 22, and whether the voltage is applied to the electrical conductor 11 is decided.
