Abstract
A power distribution network monitoring system includes a CT sensor and a power management device. The CT sensor includes a measurement component and a transmitter. The measurement component is installed at a plurality of predetermined positions along a power line constituting the power distribution network, and measures current of the power line at each predetermined position. The transmitter wirelessly transmits, as transmission data, the power spectrums of the fundamental wave, third harmonic, and fifth harmonic, as well as the effective current values used to detect abnormalities in the power distribution network, the data being at least part of the data measured by the measurement components. The power management device includes a receiver and a management database. The receiver receives the transmission data. The management database stores the received data.
