System apparatus and method for monitoring condition of underground cable

摘要

A ground cable status monitoring system according to an embodiment of the present invention includes a sensing device disposed in the ground and sensing at least one of temperature, immersion, leakage, oil pressure, displacement, and deterioration of an underground cable; A power supply for generating power dependent on the current flowing in the underground cable and for supplying power to at least one of the sensing device and the wireless data transmission device; And a data collection device disposed in the mobile device moving on the ground and transmitting a mode control signal for changing the mode of the wireless data transmission device and collecting the sensed data, wherein the mode of the wireless data transmission device If you change from inactive mode to active mode and after inactive transmission of the detected data, The draw may be changed.
