A voltage measurement device includes a probe module movably arranged around an alternating-current transmission line, and a measurement unit. A metal electrode is arranged on a surface of the probe module facing toward the alternating-current transmission line, electrically coupled with the alternating-current transmission line to form a coupling capacitor, and then forms an electrical circuit with an inductor element, a resistor element, and a reference signal source in the measurement unit. A processor controls the reference signal source to input reference voltage signals at different frequencies to the electrical circuit, determines a resonant frequency of the electrical circuit according to currents of the electrical circuit under the reference voltage signals at different frequencies, and determines a voltage of the alternating-current transmission line according to a first current component amplitude and the resonant frequency of the electrical circuit. A voltage measurement method and a storage medium are also disclosed.
