The invention belongs to the technical field of electric power construction safety equipment and particularly relates to an overhead line ground electroscope and an electricity verification method. The overhead line ground electroscope comprises a coupler, an amplitude limiting amplification circuit and a voice output circuit, the coupler is connected with the amplitude limiting amplification circuit, the amplitude limiting amplification circuit is connected with the voice output circuit, the coupler is close to or movably connected to a ground down lead of an overhead line in a sleeved mode, collected currents are transmitted to the amplitude limiting amplification circuit to be processed, a signal with the strength suitable for being applied to the voice output circuit is formed, and the voice output circuit receives the signal and then gives out a voice prompt. A coupling method is adopted, whether the overhead line is carried with electricity or not is judged by detecting whether currents exist in the ground down lead or not on the ground, electricity verification can be conducted without the need of climbing on a tower, in the electricity verification process, the personnel are away from electric facilities, and operation is safer; the overhead line ground electroscope is reasonable in design, simple in structure and convenient to operate.
