| Zusammenfassung: | The utility model provides a phase to earth fault seeks device has adopted to two kinds of signals of earth fault circuit injection high voltage signal and ultralow frequency constant current signal, realizes wireless receiving trouble leakage current signal, seeks location single -phase earth fault point. The device has included: high voltage signal source, super low -frequency signal generator, signal conditioner, AD converter, singlechip, display, high -pressure current clamp, electric current signal acquisition module, radio signal sending module, radio signal receive module, signal processing module, LCD, low -frequency signal generator 0. After transmission line took place phase to earth fault, it provided practical inspection instrument to become power operating person, and phase to earth fault can conveniently be fixed a position to the device, had practicality, portable, laborsaving, the characteristics that save time. |
