Fault addressing device for electric transmission line

The invention discloses a fault addressing device for an electric transmission line. A pilot frequency standing wave standing wave method is adopted by the faulting addressing device for addressing. The fault addressing device comprises a precise frequency sweep circuit, a storage unit, an output unit, a data processing unit, an image interface module, a structure module, a storage module, an output module, an anti-interference module and an error correction module. The fault addressing device has the advantages of small volume, convenience in carrying, low cost, dual purposes of alternating current and direct current of a built-in battery, interface pattern digitization and simple and visual operation, and fault addressing can be finished in a transformer substation; and what is more important that the addressing precision is high, so that the working efficiency can be greatly improved, more precious time and a large quantity of manpower, financial resources and material resources can be saved for the power
