Patent number: 11579214Abstract: A cable condition monitoring sensor device includes a TMR magnetic field sensor module, a high-pass filtering module, and a signal-amplifying module which are sequentially connected. The TMR magnetic field sensor module measures a magnetic field change signal of a cable, converts the same into a voltage signal, and outputs the voltage signal to the high-pass filtering module. The high-pass filtering module filters out DC bias of the voltage signal, and transmits the filtered voltage signal to the signal-amplifying module. The signal-amplifying module amplifies the filtered voltage signal to obtain an output voltage signal and outputs the output voltage signal. In the present invention, a common mode current to be measured in the cable is extracted by placing the magnetic shielding ring made of ferromagnetic material outside the cable to filter out a differential mode load current in the cable, and the magnitude of the common mode current is determined.Type: GrantFiled: April 16, 2020Date of Patent: February 14, 2023Assignee: Tsinghua UniversityInventors: Pinjia Zhang, Yang Wu
