Abstract

PURPOSE: To enable an operation for easily locating a disconnected position in the distribution line, by a disconnection position indicator coming to be operated due to a change of peak value of voltage across initial ends of the distribution line caused in accordance with the disconnected position in the distribution line.
CONSTITUTION: If a disconnection is caused in any one of the distribution lines, a peak value of voltage across initial ends of the distribution line the disconnection is caused reaches at least the constant voltage of a constant voltage element 5b, causing a constant voltage element 6c at least to conduct, and any one of the light emitting elements d1, d2, d3, corresponding to the disconnected distribution line, will emit a light with the disconnection made known to be located in what distribution line
