Embodiment Construction
[0061] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0062] The terminal has the function of "two remotes", which can upload the zero-sequence transient current characteristic data to the master station through GPRS. Installation tests are carried out on site.
[0063] This embodiment includes the following steps, as attached figure 1 Shown:
[0064] (1) The terminals installed at multiple locations on the line detect the transient zero-sequence current at the installation locations in real time.
[0065] (2) When the zero-sequence voltage amplitude detected by any terminal exceeds the preset start-up va...
