The invention relates to a sheath cable state comprehensive monitoring device and a stealing and cutting monitoring method, wherein a Rogowski coil is adopted to output a low-voltage signal to monitorthe current of a sheath cable so as to avoid the danger of a detection signal to a user, and the collected values of the sheath current and the operation current are used to determine the phase of cable stealing and cutting. The monitoring device and the monitoring method provided by the invention are simple in construction, low in cost and high in accuracy. 本发明涉及一种护层电缆状态综合监测装置以及盗割监测方法，通过采用罗氏线圈输出一个低电压信号对护层电缆的电流进行监测，避免检测信号对于使用者造成的危险，并且利用采集到的护层电流和运行电流的值对发生电缆盗割的相别进行判定。本发明提供的监测装置以及监测方法，施工简单、成本低廉、并且准确性高。
