Document Type and Number:
Japanese Patent JP7199651
Kind Code:
B2
Abstract:
To provide a detection device capable of identifying a state of an electric line to be measured from an analysis result by analyzing a leakage current.SOLUTION: A detection device includes: a leakage current detection part 11 for detecting a leakage current flowing to an electric line to be measured; a voltage detection part 12 for detecting voltage applied between two phase of the electric line to be measured; a phase difference detection part 13 for detecting a phase difference on the basis of a leakage current detected by the leakage current detection part 11 and voltage detected by the voltage detection part 12; and an identification part 14 for showing a leakage current by a vector by disposing the leakage current detected by the leakage current detection part 11 in a position on coordinates fixed by a phase difference detected by the phase difference detection part 13, analyzing a change amount of vectors of at least two leakage currents, and identifying a state of the electric line to be measured on the basis of the analysis result.SELECTED DRAWING: Figure 2
