Kind Code:
A1
Abstract:
This power distribution network monitoring system (10) has an LTLS (7), a reception part (53a), and an abnormality determination unit (56). The LTLS (7) has a detection and power supply part (71), a transmission part (76), and a counter part (75e). The detection and power supply part (71) is installed at each of a plurality of predetermined positions on a power line provided in a power distribution network (100), and performs electrical measurements of the power line at each of the predetermined positions by using the current that flows through the power line. The transmission part (76) transmits a result measured by the detection and power supply part (71). The counter part (75e) counts the number of transmissions made by the transmission part (76). The reception part receives the transmitted measurement result. On the basis of the received counter value, the abnormality determination unit (56) determines at least one among the occurrence of a communication abnormality and the occurrence of a power line disconnection.
